Fill the glass jar with water and cover it with a card. As you turn the whole thing upside down, the audience can hardly contain themselves. The room quiets down as you precariously position the inverted jar and card a few feet above someone’s head. And yes, I love the look of terror on my “helper’s” face when I take the card out from under the jar. Watch the video below and read the experiment for a lesson on how to make some science magic.

    Hey Steve just wanted to say thanks for all of the awesome fun experiments that you demonstrate. So many kids and teachers make good use of them. I Did the floating water with my kids and taught them all about air pressure while having some good old fashion science fun. Apprecaite it greatly!
