Video: Everyone knows you can't fold a piece of paper more than seven or eight times (even though the world record is 12). It's just one of those silly things that stick from primary school and become law. But what if you were folding aluminium foil? And what if you had the assistance of the almighty hydraulic press? You can fold pretty much forever! Watch the silly fun video below. It shows how a sheet of aluminium foil can keep getting folded and then smashed and then re-folded and then re-smashed, again and again and again. Even when it's folded 26 times over, it looks pretty much the same as after the first few folds.
