Description
A simple design that demonstrates a powerful concept: atmospheric pressure! Place this rubber mat on any flat surface and pull on the handle. It's like the mat is glued down!

The demos started off well, we were able to lift plastic carts that we use to move things. However, after using them for a period they lost their ability to stay sealed rather quickly. I did not take force measurements. It appears to tend to "buckle" starting from the same side repeatedly. Perhaps a thicker sheet of rubber/silicone would be better.

This is a very simple trick utilizing a scientific principle! With this 12" x 12" mat, at 14.7 lb/sq.in. gives 2116.8 pounds of force required to counter it! Over a ton of force! Amazing from our powerful invisible friend!

The hook lifts the mat a little too much so it is easier to pull up than i would like, still a very popular demo
