Today's challenge: Build a tower as tall as you can from whatever you can. Make sure it doesn't fall over (or at least photograph it before it does!). You can use whatever is to hand. Make it beautiful, or just make it functional. Work as a group or on your own. See how tall you can go.
I made a tower out of loo roll. This was my third attempt (the other two fell over before I could take a photo). Loo rolls do not make solid construction material. I think I could have gone higher, however, but I ran out of rolls.
