My children are completely obsessed with the test tubes I bought for the Harry Potter Fan Birthday Gift. They have been filling them with everything from pebbles to gak to candy. I decided to take a look at what else you could do with test tubes and I'm amazed at the ideas. LOVE the test tube soup shooters and the memory test tubes. Take a look at this Pinterest Board for inspiration. And if you're in the market to buy them, I found mine here. (These are small, so they fit candies like nerds or pixie sticks). If you're a prime member, they'll for sure be here before the Halloween Parties! And our labels with be perfect for them!
