Discover the secret here http://www.stevespanglerscience.com/content/experiment/magic-spheres "For this trick, all you need is a bit of un-popped pop corn and a ball bearing." It's the perfect phrase to get all of the people around you excited for a bit of science magic.

Everyone knows that a balloon's worst fear is a sharp object...even a sharpened, wooden cooking skewer. With a little scientific knowledge about polymers you'll be able to perform a seemingly impossible task...

All these people are laying down, by why aren't they falling? They comprise a human table!

Table tricks are a great addition to any meal. Do you want to whip the tablecloth out from under they place settings? Great! Oh, you're trying to move a toothpick just by using a singing wine glass? That's awesome, too! But what if you want to turn all of your guests INTO a table? Well, lucky for you, we have the perfect trick... the Human Table Trick!

1. Set up four chairs in a square. The chairs need to be close enough that a person can lay backwards and have their shoulders rest on another chair.

2. Have four friends sit in the chairs. The friends need to have their feet on the ground.

3. Each friend needs to lay backwards, resting their shoulders on the legs of the person behind them.

4. One by one, remove the chairs from under your friends.

5. Much to their amazement, your friends remain in their reclined position, despite lacking the support of the chairs.

6. Before your friends collapse, replace the chairs and let them sit-up. Ta-da!

That's incredible! Your friends create a table that is practically sturdy enough to eat off of... but how does it work?

When you remove the chairs from under your friends, the expectation is for your friends to crumble to the floor in a giggling mass. Instead, they remain stable (even if they're still giggling). The secret to this table-esque trick is a system of balanced forces. Even though gravity is pulling your friends down, each friend is supported by the legs of the person behind them. With each person being supported, the only question is when your friends' legs give out.

How many friends can you get to form a table? All you need to do is get more chairs, then you can have a table made up of as many friends as you want!

Here's an easy-to-do experiment using only a balloon and a hex nut from the hardware store. This is the perfect science of sound activity because kids will love it and parents will be left shouting, "STOP!" Be sure to buy enough supplies for all of your friends.

Read the full experiment at http://www.stevespanglerscience.com/experiment/spinning-match-table-trick When you cautiously balance a matchstick on the rim of a coin that has also been precariously balanced onto another coin, it might sound like rotating the matchstick will cause it all to come tumbling down. We'll show how this isn't just possible, it's downright cool.
