Squishy Slime Balloon Science Experiment
In this fun and easy science experiment, we’re going to make a squishy slime balloon.
- Liquid starch
- Pour about ½ cup of glue into a mixing bowl.
- Slowly mix in about ¾ cup of liquid starch.
- Keep stirring the mixture until the slime begins to solidify.
- You want the slime to stiffen to almost the consistency of silly putty. Feel free to add glue or liquid starch as needed.
- Allow your slime to sit for several minutes while you take the scissors and cut the neck off of a balloon.
- Insert your fingers into the balloon and stretch it open.
- Work a good sized ball of the rubber slime into the balloon.
- Tie off the end and enjoy.
How it Works:
The liquid starch contains a chemical called sodium tetraborate. The sodium tetraborate links the polymers in the glue together creating slime.
Make This A Science Project:
Use other activators like contact lens solution or Borax to create the slime and observe any differences. Try different types of glue like clear glue. Try different brands of glue.
