Who doesn't love a good magic trick? Demonstrate this entertaining "illusion" to your child and educate her about water pressure at the same time! You will make it look like a single piece of card is holding an entire cup of water in a glass. Your child will be excited to learn about the science of air and water pressure, the logic behind this wizardry. A word to the wise: This experiment can get a bit wet, so it is probably best to perform this spell in a kitchen or bathroom, where scientist slip-ups can easily be mopped up.
