How Does It Work?
Fill the glass jar with water and cover it with a card. Have one of your braver students or friends stand under the jar as you turn it over above his or her head. Note the amazement on the faces of your audience, but it's nothing like you'll see in a minute when you pull the card away from the overturned jar and dump the water on your unsuspecting—but hey, what happened? Hope you don't mind a few screams. Who's next? Think you can do it again? Of course you can. It's a science experiment!
What Does It Teach?
Learn all about water molecules, including how they cling to each other forming "surface tension." Discuss how air pressure works to keep the water from spilling all over your poor volunteer, and last but not least, brush up on your acting skills!

Just want to say that I had my grandsonsages 7, 9 and 11 perform this and they had a plast, they had a hard time putting it down. (Posted on 4/3/13)
- Works great Review by Jenny Brown
This worked great, but wasn't exactly as spectacular as the picture. I bought it as a prize for a teen event and the teens loved it. I think I was a little disappointed because I had seen the picture. I put food coloring in the water because it makes it much easier to see and a lot prettier. (Posted on 3/21/13)
