DIY ☀️Solar 🌎System Craft From ❌♨️No-Cook Natural 🏡Homemade Play Dough 

As a tribute to National 🚀Space Day, which is held annually on the first Friday in May, we are making a DIY Solar System craft from homemade no-cook natural play dough.


 To explore our solar system and the planets, we read National Geographic Kids First Big Book of Space which is kids' absolute favorite Space book with colorful illustrations and simple text, explaining basic concepts of the universe as well as its wonders!
DSC_0122First, to resemble Space, Adrian made black play dough. ( See the recipe and details on how to make this natural play dough here ~in a post "No-Cook Homemade 🌈 Play Dough Recipe.")
DSC_0122Next, apply glue to a large cardboard piece and spread the black playdough over it.
DSC_0122Leave empty the space for the sun as it will be easier to glue the Sun to the cardboard rather than over the play dough. 
DSC_0122To resemble our universe and the sparkling twinkling stars, galaxies, and supernovas, we are adding glitter to our black play dough.

DSC_0134 We are using this iridescent and this chunky-holographic glitter.
DSC_0134Did you know that stars come in different colors and sizes? From blue to orange to red!

DSC_0134Yellow glitter adds shine and sparkle to our yellow Star.

DSC_0134Next, trace planets on a cardboard. We are using this book for size-reference.

DSC_0134Glue the Sun to the part of cardboard that has no play dough. 

 Earth Play DoughMake each planet (by spreading the play dough over the cutout cardboard piece) according to planet's characteristics, such as size, color, surface.

Finally, arrange the planets in order: 1) Mercury, 2) Venus, 3) Earth, 4) Mars, 5) Jupiter, 6) Saturn, 7) Uranius, 8) Neptune. Discuss the four terrestrial planets, separated by the asteroid belt from the four gas giants. Bring child's attention to any distinguishable planetary detail: such as The Great Red Spot on Jupiter (a huge storm raging on for hundreds of years) or Neptune's The Great Dark Spot (a huge spinning storm in the southern atmosphere of Neptune which was about the size of the entire Earth). 

DSC_0160You can also discuss the solar flares and winds and how the Earth's magnetic field interacts with the solar wind and acts as a shield to protect Earth from damaging solar particles.  See a video from NOVA’s Sun Lab here


We also watched an amazing series NOVA - Origins which presented some startling new answers to questions such as "Has the universe always existed? How did it become a place that could harbor life? Are we alone, or are there alien worlds waiting to be discovered?" Both, Julia ( 8 yo)  and Adrian (4 yo) were absolutely intrigued and engulfed in this miniseries ~an absolute must-have DVD for any inquisitive child (or an adult)!

DIY 🌘Moon Craft • Baking Soda Acid-Base ⚗️Science Experiment

As a tribute to National 🚀Space Day, which is held annually on the first Friday in May, we are making a DIY Moon craft, but first, we learn about it. The Moon is about 4.5 billion years old. There are three theories as to how our planet's satellite could have been created: the giant impact hypothesis, the co-formation theory, and the capture theory. The prevailing theory, the giant impact hypothesis suggests that the moon formed when an object, known as Theia, the Mars-sized body, collided with Earth, throwing vaporized chunks of the young planet's crust into space. Gravity bound the ejected particles together, creating a moon that is the largest in the solar system in relation to its host planet. This sort of formation would explain why the moon is made up predominantly of lighter elements, making it less dense than Earth — the material that formed it came from the crust while leaving the planet's rocky core untouched. Read more interesting facts about the Moon here


This DIY Moon craft is a fun project to express creativity while learning about the Moon and conducting a science acid-base reaction experiment. Detailed instructions are below.

DSC_0046Trace a circle on a cardboard. 

DSC_0046Cut out the circle and set aside (you won't be needing it for this DIY).

DSC_0070Take another cardboard piece and trace another circle on it and pour glue in the middle.

DSC_0070Pour baking soda on top of the glue.

DSC_0070Now, invite your child to put on a scientist cap on and perform an acid-base reaction experiment by squirting vinegar over the baking soda. 


We have done a few acid-base reaction experiments, and children never seize to be amazed by the bubbles and the fizz.

DSC_0070Next, we added few drops of diluted black coloring to give the Moon its grayish look.

DSC_0070Finishing off the moon with glitter. 


Now, going back to the cardboard where the circle was cut out, paint it with blue and purple color (we are using these washable finger paints). And, to exercise those fine motor skills, offer the child to paint with a pom pom while holding the pom pom with a peg.

DSC_0070 We ended up with a dark ~ galaxy like-color.

DSC_0070Add glitter to the paint while it is still wet.

DSC_0070More glitter! This time holographic chunky glitter. 

DSC_0110Now, have your cardboard pieces ready as you will be gluing one on top of the other. 

DSC_0110   Use a glue-gun to adhere the two cardboard pieces together. 

DSC_0110 Let it dry, and your Moon craft can be framed to decorate a wall in your child's room.  

I hope this Moon DIY will spark questions such as "Why do we only see one part of the Moon?" or "Why there are craters on the Moon?" and so forth.

DIY 🌌Galaxy Baking Soda Borax-Free 🏡Home-made ❌Non ♨️Toxic Slime • Kids 🙌🏻 Sensorial ⚗️Science Experiment

Inspired by the approaching 🚀National Space Day, which is observed annually on the first Friday in May, we are making galaxy slime. Trust me, your kiddo will love this no-mess sensory glittery stretchy goo, and so will you!  This DIY version of slime can be easily made at home with materials you probably have handy. And, we are making a non-toxic version of the slime, so no borax is needed!

DSC_0030First, we research how does the galaxy appear from space. Did you know that stars come in different sizes and colors? Blue stars are the hottest and red are the coolest. And, in between, you have yellow stars (our Sun), orange and white. So, although to us, the stars look like twinkling white diamonds, the galaxy is actually sparkling with a rainbow of colors! For our reference in creating our galaxy slime, we are reading the National Geographic Kids First Big Book of Space (buy here) which is our absolute favorite Space book! 

DSC_0067What you will need for this super easy home-made 🌌Galaxy slime:

  • 1/2 cup of liquid clear glue (buy in bulk here) or use this purple washable glue,
  • 1/2 teaspoon of baking soda which helps firm up slime,
  • food coloring (add more of blue and purple if you are using a clear glue) and glitter,
  • *[last step] add 1 squirt of saline contact solution ~ please, do not add too much as the slime will not be stretchy! You can always add another squirt of the solution, but start with just one ~ for a 1/2 cup of glue, it is generally enough! 
  • Note: we do not add water! Contact solution is enough! And, add your contact solution last (after you have added all your glitter and food coloring) since once the chemical reaction of bonding and changing the composition begins, it will be difficult to mix the ingredients!)

DSC_0067Slime is made when the activator ~ contact solution mixes with the polymer chains in the glue, creating strong but flexible bonds between the molecules. 

DSC_0067What is the ⚗️ science behind the slime?  Baking soda makes slime firm and the saline solution is the slime's activator which helps slime get its rubbery texture. Please note, that some recipes use Borax (white, powdery, naturally occurring mineral often called sodium borate), which also has boric acid but we avoid using Borax since it is toxic; and we use contact solution instead. Please note that Borax and boric acid are not the same, although they are from the same boron family. Contact solution, on the other hand, has both boric acid and sodium borate (all members of the boron family) which are the best slime activators, helping to form the stretchy slime your kids love so much!

DSC_0067The slime forms when the mixture of boric acid and sodium borate ~ cross-linking agents both present in the saline solution ~ begin to bond. These two "magical' ingredients create your awesome slime! The last step is to mix your slime with the fork and then knead with your hands. The slime is ready once it starts to pull away from the sides of the mixing bowl.

DSC_0067And, of course, Adrian had to make blue SKY slime, as blue is currently his favorite color. 

DSC_0067The ⚗️mystery of glue: glue is a polymer made up of long, repeating identical strands of molecules. These molecules generally freely flow past one another keeping the glue in a liquid form. However, when you add the borate ions to your slime mixture, they begin to connect these long polymer glue strands together, tangling and mixing until the substance is thicker and rubberier like slime and less like the liquid glue you have started with.


This simple slime recipe is an ultimate guide on how to make galaxy slime at home with just a few non-toxic ingredients! And, the best part, this slime is re-usable! Just store it in an air-tight container (like those recycled jam jars) and use it over and over again! We are still using slime that we made six months ago! 


I hope this glittery, sparkly, stretchy slime will keep your child stimulated and entertained for hours! Enjoy this sensory fun and don't forget to let your kiddo have a turn (you might get carried away playing with it yourself!)


We also made slime during Christmas holidays, see here ~ 🎅🏻 Santa ❤️ Red Slime DIY Jar (Science 🔬⚗️⚖️ 101 🎥Series 🎇).

Soft Shelled 🏐Bouncy Raw 🐣Egg Kids 🔬⚗️⚖️ Science 101 🎥 Series 🎇

Science experiments are super fun to conduct at home with common household items. The science concepts applied in school or in a lab are the same, and kids are astonished by simple hands-on activities that nearly any parent can accomplish. So, how about a raw egg and vinegar experiment! Like magic, the eggshell will slowly dissolve, leaving behind a bouncy egg.


What you will need:

  • 1 uncooked raw egg in its shell (you may also use a hard-boiled egg, which is less messy if you accidentally break it),
  • 1 cup of white distilled vinegar (acetic acid) which will be the main chemical used for the experiment,
  • a clear jar or a glass.


  • pour 1 cup of vinegar into a glass,
  • add the egg ~ make sure that the egg is completely covered with vinegar.
DSC_0004Bubbles should appear in vinegar, especially on the eggshell's surface.  

DSC_0057Observe bubbles rising from the egg. Leave the egg in vinegar for one day.

 DSC_0057After 24 hours, large bubbles should form all over the eggshell. You may notice some pieces of the shell at the top of the liquid in the jar. Remove the egg and rinse it in water.   

DSC_0057The eggshell is soft (for now). Note, that if left for one week, the entire eggshell would be dissolved by the vinegar.

⚗️Science Mystery is Revealed: the eggshell is dissolved because vinegar is an acid and the eggshell contains calcium carbonate, which is a base. Calcium carbonate is what makes the egg hard. Vinegar is an acid known as acetic acid. When these two chemicals: calcium carbonate (the egg) and acetic acid (the vinegar) are combined, a chemical reaction occurs and carbon dioxide (a gas) is released. Bubbles are made out of this gas. Such chemical reaction keeps occurring until all of the carbon in the egg is used up: it takes about a day. After 24 hours, all the carbon from the eggshell is released. So now, when you take the egg out of the vinegar, the egg is soft because all of the carbon floated out of the egg in those little bubbles.


Did you know that if you remove the egg after sitting in vinegar for one day and then left it out on the table for another day, the shell would become hard again because the shell would take carbon from the outside air. (The calcium left in the egg shell would steal the carbon back from the carbon dioxide that is in the air we breath.)


  1. With a raw egg, once the shell has softened, place the egg in the water again and it will absorb and expand through the osmosis process until the shell finally bursts.  
  2. Bones: What makes our bones hard is calcium carbonate ~ the same compound that makes the eggshells hard. So, make an experiment and take some thin chicken bones (e.g the wishing bone) and drop it in vinegar and leave for a day. After 24 hours, such bone will be soft just like the eggshell was. The bone will be bendable like a sting ~ try to tie it in a knot, I bet you will succeed! However, if you leave the  knotted bone sitting out on the table, it will get hard again, just like an egg!

🖌Markers ☕Coffee Filters 🌈Rainbow Walking 💦Water ⌛️Timelapse Kids ⚗️Science Capillary Action

Today, we are using materials you probably have at your home such as ☕️coffee filters and markers to conduct this amazing chromatography tie-dye color mixing walking 🌈 rainbow experiment! 


What you will need:

  • white coffee filters,
  • little glass jars, shot glasses or small drinking cups,
  • markers in rainbow colors (do not use Sharpies, crayons, pencils, solid tempera paint ~ trust me, we tried it all! only these type worked for us),
  • water (see tips 👇🏻 below). 

DSC_0001Invite your child to draw a large circle at a base of a coffee filter. 
DSC_0001Do the tracing over scrap paper or a newspaper as the markers bleed through.
DSC_0001By tracing just the base-circle,  your marker will not bleed too fast otherwise turning the whole filter one color instead of tie-dye!   DSC_0017Fill glasses with a little bit of water (about an inch).
DSC_0017 The way you fold is important❗️Fold your coffee filters in half. 
DSC_0017Fold them in half again.
DSC_0017Fold each filter for the third time ~this will expose the white un-markered center at the point.DSC_0024Insert folded filters into jars/shot glasses.DSC_0028For tie-dye effect, make sure that only the tip of filters is touching the water ❗️DSC_0028
The water travels fast ~ within few minutes, you will be seeing the result of the process called capillary action!DSC_0028 
Capillary action is a process during which liquid, like water, moves up into a material with a lot of small holes (like paper ~ coffee filter).

DSC_0051Capillary action happens when three forces called cohesion, adhesion, and surface tension work together.


In other words, capillary action occurs because water molecules bond together due to forces of cohesion and adhesion as well as stick to other substances such as paper (coffee filters). 

DSC_0051The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules.  DSC_0069 Adhesion of water to the surface of the material (coffee filters) will cause an upward force on the liquid (water). Notice, that the remaining (non-absorbed) water in glass jars remains clear! 

DSC_0074   A voila! A beautiful 🌈rainbow! DSC_0074  ⌛️30 minutes later ~ do you see the tie-dye effect!
DSC_0074Purple was Julia's favorite, while blue was Adrian's choice! DSC_0074

Once the capillary action is completed (30-40 minutes), take the filters out of the water and let them dry.
DSC_0074I suggest air drying filters first until the colors settle (clothespins do the trick!). Otherwise, the color from filters will transfer to the drying surface. After about ten minutes, we had rainbow coffee filters to create a craft with!

DSC_0097What to do with these beautiful rainbow filters? What about a rainbow flower! Just fold each filter from the center, crinkle it individually and hold all the filters together!

DSC_0074Or, insert a green pipe cleaner at the center of a filter, threading it through, then thread the next filter, till all filters are on a pipe cleaner ~ tie the tip of the pipe cleaner in the center and crinkle the filters up.
Rainbow flower! This can make a perfect💐Mother's Day🎁Gift too!

DSC_0028 We did a similar flower craft when Adrian, as a tribute to Van Gogh's Birthday, made 12 🌻Sunflowers Tissue Paper Recycled Cardboard Roll Paper-Mache Craft (see 📽️ a video of him making it here).
