🎅🏻 Santa ❤️ Red Slime DIY Jar (Science 🔬⚗️⚖️ 101 🎥Series 🎇)

Today, we are making Holiday slime. It has been on my to-do list for a while now, and we are very excited to finally conduct this sensory learning experiment! Slime, besides being absolutely awesome to touch, is also an amazing science demonization. We love hands-on learning through play, and slime is a perfect activity to get children excited about chemistry! 
DSC_0042What you need to make a homemade slime:

  • 1/2 cup of liquid clear glue (buy here),
  • few tablespoons of saline contact solution (buy here) or liquid starch (buy here); some use borax which also has some boric acid but we avoid using since it is toxic). Boric acid and sodium borate are the best slime activators.
  • 1/2 teaspoon of baking soda, which helps slime firm up,
  • coloring,
  • glitter,
  • slime foam balls (buy in bulk here),
  • confetti stars. 

DSC_0043Pour glue into a bowl. Add glitter and liquid color. Stir until uniformly distributed.

DSC_0043Add contact solution and mix until thick and slimy.

DSC_0043Add little styrofoam micro-beads to your slime to make foam.
DSC_0043Add star confetti and mix well.
DSC_0043Mix and then knead the slime with your hands. If it feels loose, add more solution.

What is the ⚗️ science behind the slime? Baking soda helps to firm slime. The saline solution is the slime's activator and helps it to get its rubbery texture. The slime will begin to form immediately thanks to the mixture of boric acid and sodium borate present in the saline solution. These two ingredients are cross-linking agents that create your slime! The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is thicker and rubberier like slime and less like the liquid you started with. The final step is to knead your slime. The slime is ready once it starts to pull away from the sides of the bowl.

DSC_0041But where to store your slime which can last for up to a week?

What you need for this DIY Santa Slime jar:

  • recycled baby food jar,
  • picture of Santa (we are using a cover from a notepad), 
  • pompoms,
  • a glue gun.

DSC_0080Glue two large pompoms to the top of the jar. 

DSC_0080 Glue Santa's picture to the pom poms. 

DSC_0080Fill up your jar with slime.

We love hands-on learning through play. Slime = science = kids explore, while learning and having fun in the process. And adding a craft element to the science experiment makes the activity even more multidimensionally exciting! 

DSC_0080Store your slime in a container with a lid and enjoy it for over a week.

DSC_0080Our Santa is very happy to see White Christmas!
