Question of the Week suggestionsEach week we ask a question. The idea is to generate material that's:
* interesting to read, i.e. we won't get bored of reading the answers after about 10 of them
* not been asked on this site before
* fun to answer
What would you like to ask? (We've left this question open - so feel free to drop in ideas anytime.)

Paper airplane launcherMade out of chipboard, door catch, elastic, blutack and bits of skirting board.
It was a work of art.
In fact, have a picture or two...
The plane is held in the pincers, and the whole assemblage is pulled back. When it is let go it travels down the runway where the bit of skirting board hits the catch, releasing it and allowing the elastic bands to pull the arms apart, releasing the plane.
I love A level Physics...
