How to make your own robot
 Guess what(don't actually guess)? This is really, really cool. If you get a balloon, ground coffee, and a vacuum, you could make your own gripping robot. First pour ground coffee into a balloon until it is completely filled. Then, blow the balloon up. not all of the way. Next, stretch the balloon hole around a vacuum . Finally,choose an object to practice on, like a piece of paper and put the balloon on it's edge. now turn the vacuum on. The balloon should cling on to the object and stick.
Explanation: Ground coffee is like water. It is like water because it's made up of small parts. Water takes the shape of a solid and so will this. When you fill it up with air it won't take the shape of an object, but if you use a vacuum it will because the vacuum will suck the air out and the balloon should cling onto an object.
