simple machine build ideas (from junk)?
i run a pub & we also have a successful themed pub quiz once a week. it's always a little bit different...
in the past we've had teams make an egg throwing machine from bits & pieces such as garden cane, plastic milk cartons etc.,(a surprisingly forceful trebuchet was the eventual winner) & we would like to do something similar.
a machine to transport something? i'm having a massive creative block so some input would be great.
ta in advance.
