Use Elmer’s Glue GAK to simulate the movement of a glacier.
If you’re old enough to remember Silly Putty, you may remember what it felt like to roll it up into a ball in your hand. The fascinating thing about Silly Putty is that you can put a ball of it down on the table and, eventually, it spreads itself out. How does it do that? Here’s a simple way to make your own version of this popular toy called GAK using household materials. You’ll use the recipe to make a white and a blue batch of GAK, give them a little twist, and use the concoction to learn more about the movements of real glaciers.
