Here's something you can all try at home if you want to, get a glass or cup of reasonable height, get a spoon and fork, get a matchstick. Link the spoon with the fork (as picture) be careful when you couple them it can be tricky! Insert the match in the centre of the fork between the middle prongs (see picture) now you're ready to go.

Set the now joined spoon and fork with the match inserted on the lip of the glass and carefully balance it so when you let go it miraculously hangs there defying gravity! It looks impossible doesn't it? But there it is before your very eyes.

The excercise demonstrates forces and counter forces related to physics, but do you know what they are?

Have fun, let me know how you did.
