What you'll need:
1/2 cup water + 1/4 cup for later
1/2 teaspoon Borax
Food coloring (optional)
Baggies
- Pour the glue into a bowl with 1/2 cup of water. Mix well.
- Add the food coloring if you'd like a fun color (if want to get really fancy, add some glitter too!).
- In a new bowl, mix 1/2 tspn of Borax with 1/4 cup of warm water. Stir until the Borax is dissolved.
- Pour the Borax water into the glue mixture.
- Now stir, stir, stir! The more you stir, the firmer it will get!
This is a messy project, so be sure to prepare your work space! There's lots of chemistry behind this activity, so this is also a good learning experience for the kids. Have them research why the gak is firmer the more you play with it and thinner when you let it sit.
The gak will last quite a while stored in a ziploc bag, just make sure it's closed tight when you put it away for the night!
