We made GAK at Crafternoon – you can make it, too.

Yesterday, we made GAK at Crafternoon. It was such a hit! GAK is a polymer made from glue, water and Borax. It’s gooey, slimey, bouncy, stretchy, and not very messy at all. Here’s our video showing how to make it. NB: There is one small error in the video — instead of two teaspoons of Borax to 1/2 cup of water, the correct ratio is 1 teaspoon Borax to 1/2 cup water.

For detailed written instructions, and a lot of info on the science behind GAK, just visit Steve Spangler Science. (Steve recommends stirring the GAK. We shook it in little plastic food storage cups with tight-fitting lids. Either way is fun.)

Experiment: Passing a skewer through an inflated balloon

Erin S. and Sarah K. LOVE our new book, Super Science Lab from DK Publishing ($8.99 at Pufferbellies). They’ve been trying out lots of experiments from the book, including making ice cream in a bag (video to come) and passing a skewer through an inflated balloon without popping the balloon. What’s that you say? Impossible? NO! Evidence here:

Super Science Lab is chock-full of fun, interesting experiments that you can do with objects found around your house (or purchased very inexpensively). We highly recommend it.

Geodes: break your own!

We got our first-ever shipment of little break-your-own geodes in stock today. We got really excited and couldn’t wait, so we took a few outside to try.

Here’s the video of what happened:

And here are two glamorous photos of our geode, after I cleaned it up a little with a toothbrush and some water. Isn’t it neat?
