This product is a pair of colorful strings that go through two plastic blocks. By pulling the strings, you show that they actually pass through the blocks. But here comes the magic, as you slide the blocks, the strings change position!
The best part is that this trick works by itself and you can do it as many times as you want. Plus, the blocks are pocket sized, so you can take it with you everywhere you go.
