Some people have too much time...

This is one of those challenges that are great for kids over the summer holiday. Kinda like eating 3 crackers in a minute or eating a doughnut without licking your lips. The task is easy enough:

Using 12 cups (paper or plastic, it doesn't really matter) stacked anyway you like, you must make 3 pyramids, the first is 2 cups wide(3 cups overall), the second is 3 cups wide(6 cups overall), and the third is 2 cups wide again. Then you have to restack them, and then do 2 pyramids both 3 wide. Restacking again, then you need to do a single cup, a 4 wide pyramid(10 cups overall), and another single cup. Finally you restack them all.

See how quickly you can do this, then try and beat this young lady...
