Crafts with Slime: Rainbow Slime & Sand Slime

All kids love playing with slimy, sticky slime, and let’s be honest, the clay is great for adults, young people, and your little ones as well. We’re sharing crafts with slime!

Slime itself is already nice to play with, but use it for the enjoyment of these crafts takes a whole new level! Why not try including slime in your activities and crafts to excite the children at your next child’s camp!

Rainbow Slime Craft

Of all the slime recipes we have made so far, this has to be one of the prettiest mistakes you can make! Today we are sharing Rainbow Slime Craft with you guys.

Well, our unicorn project is one of our favorites too, but the colors on this vase are simply so much fun! You can have fun mixing this Rainbow for a high sensory activity for children. This is perfect for a spring activity, St Patrick’s day, or even a rainy indoor activity!

This Rainbow Slime is so colored and fun to do! The kids will love helping out with that clay. We just like how vivid the colors are!

What you need

  • 6 oz of Elmers Clear Glue
  • 1/2 teaspoon Baking Soda
  • 1.5 Tablespoons Contact Lens Solution (your brand must contain boric acid and sodium borate)
  • Liquid Food Coloring

Instructions (step by step)

You must follow the recipe and make 6 batches of slime.1 for each color. Separate them into separate jars before making your rainbow sludge.

Align the colors side by side. You won’t need to use the whole batch of each color to align them, so keep some aside to do it a few times.

Once you start mixing colors together, they are likely to become brown.

Each time you mix viscous colors, such as clay, the colors mix. However, we find it always fun to make various colors and mix them!

Sand Slime

If you enjoy kinetic sand and clay– then you should try this sand mud. It’s a mix of slime, kinetic sand, and play dough. You’ll love the texture and it’s fun to play with!

What you need

  • Elmer’s Clear Glue (6 oz)
  • 1/4 cup of warm water
  • 1/2 teaspoon baking soda
  • 1.5 tablespoons of Contact lens solution

Instructions (step by step)

Take a bowl to combine your slime ingredients.

Add 6 ounces of clear glue to the bowl first.

Stir in 1/2 teaspoon baking soda. Do not over-mix at this stage or too many bubbles will form in the clear glue.

Add 1/4 cup of water. And mix gently (to avoid creating too many bubbles).

Add a cup of sand to the bowl.

Add 1 tablespoon of contact solution for starter and mixing. Then add 1/2 tablespoon and mix until it starts to come out of the sides of the bowl.

Remove the slime and knead until it stops sticking. It will be sticky, to begin with, but if you continue to knead it will turn into perfect coherence.

You can also put some oil or baby lotion on your hands to help the glue at this stage. Do not add an extra contact solution or it will be too hard.

Repeat this process for each color of colored sand.

We hope you enjoy this fun sand slime recipe. It’s such a fun texture and perfect to do in the summertime!
