We all love building towers, making them taller and taller until ... one clumsy move ... and it all falls to the ground. Imagine now that instead of building bricks you had to use "Santa's hats". How difficult would that be? Leaves 2 were up to the challenge!

Let's count to ten again. That makes twenty. Good job!
Again. One, two ... ten. W.O.W. 30 cups for each tower. Will anyone hold if we put ten more?
Oh, team A is starting to wabble! Oh, no. It fell. But team B is looking good. It's very tall. Do you think it will last? Ok. Ten more ...
