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

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

DSC_0001

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.

DSC_0066

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).

❤️Valentines ✨Glitter Sensory 🎁Bottle ~ Calming Jar

This glitter sensory calming bottle can make a perfect Valentine's 💝gift! It is sensorily therapeutical and can be used as a mindful meditational tool for children. This Valentine's DIY craft is super easy to make, and the best part is that children can personalize their Sensory ~ Discovery bottles with a certain glitter color combination or the objects they choose to place inside. 

DSC_0030

What you need to make this ❤️Valentines ✨Glitter Sensory Bottle:

  • a  bottle ~ make sure it does not leak (ideally, you would want something tall),
  • clear glue (buy here),
  • glitter (buy here),
  • we are using plastic hearts from a craft store; 
  • a glue gun to secure the cap to the bottle.

DSC_0030Fill the bottle with clear glue about 3/4. Add glitter and hearts.
DSC_0030Make sure you leave space to add water, otherwise, the substance will be too thick.

Note: we originally filled the bottle 3/4 with glue, and although right after we made it, it worked fine, the next day, the substance was too thick. I suggest the best ratio is: fill 1/2 glue + 1/2 water.
DSC_0038Fill the rest of the bottle with hot water (hot will help dissolve the glue). The higher the water to glue ratio, the more freely would the objects/hearts float in the glue/water substance. 

DSC_0039Shake ~ observe ~foocus! "As the bottle clears, so does the mind."

A DIY Calm Down Sensory bottle can help children with sensory sensitivities or can help calm a child when the emotions become overwhelming. Focusing on the objects in the calm down jar helps a child focus the attention and calm down, being an excellent meditation technique for children. 

DSC_0039Besides this red ❤️Valentine's sensory bottle we made as a🎁gift for Daddy, we ended up with two more bottles: Adrian decided to make one for Julia (pink) and one for himself (blue) as Valentine's💝gifts.



DSC_0043I painted tops of jars: Adrian's in blue & Julia's in pink, sprinkling some glitter on top. 

DSC_0039

Besides stimulating the child sensorily, these Glitter Jars are a great meditational tool to quiet the mind, gather thoughts, find peace and inner balance, while watching the glitter swirl around and around. 

DSC_0004These sensory bottles can also make a perfect ❤️Valentine 's🎁gift.

DSC_0043-3Using a glue gun, I secured ribbon & a bow to the top of the bottle, making it a complete gift.
DSC_0043-3Happy ❤️Valentine's Day! Let your days be filled with ❤️LOVE!
