This AWESOME chain reaction is called a stick bomb. It's made by weaving popsicle sticks together to create tension. When you take the first one out, the whole thing flies apart! Enjoy!

This video demonstrates that water on its own isn't conductive. When you pass a current through it, almost none makes it out. However when you impurify it with, for example, salt, then it becomes highly conductive. Enjoy!

Hydrogen peroxide is a water molecule with an extra oxygen atom. Over time, this oxygen will be released. However, if you add a catalyst, like yeast, then the oxygen will detach much faster. Add some soap, and you've got foam! Enjoy!

This is a science experiment. If you fill 2 glasses with water that is saturated with salt, and put an end of a rag in each, water will climb up the rag due to capillary action. The water will start to evaporate from the rag and coat it will salt crystals. Eventually, if you take the rag out of the water, it will retain in its shape and seem solid. The water that drips from the rag will evaporate and form crystals as well.
