Sand Slime


How we did it:
Materials List
- school glue (1/2 cup) - white glue works best
- liquid starch (1/2 cup)
- sand (1 cup)
- mixing bowl
- craft sticks
- measuring cup
-
Gather your materials!
-
Mix 1/2 cup of glue and 1/2 cup of water in a bowl. Mix well!
-
Add in one cup of sand and mix it together.
-
Measure out 1/2 cup of liquid starch. Add about half into the mixture and give it a good stir. When it’s mixed well, add in the rest of the liquid starch. Make sure to stir around the edges to incorporate everything together.
-
For best results, let the mixture sit for about 10 minutes. (But if you can't wait that long, you can start playing with it right away!)
Tip: Store the slime in a zip bag to prevent drying out
What’s happening?
The glue contains some super-long molecules called polymers. Adding the liquid starch causes a reaction called cross-linking. Once this happens, the long polymer molecules stick to each other and forms a slime-like consistency!
