Bill Gates has posted a £65,000 bounty to the person or team that finds a way to improve the age old design of the condom. Including "designs that are easier to properly apply" which inspired our favourite weapons designer Joerg Sprave to of course apply his expertise in slingshots to the problem.

The result is a weapon tool that is sure to give any virile man second thoughts about aiming the slingshot point blank at his own hardware. However, it does appear to work as advertised, and is clearly a much easier and quicker way to apply a condom. So Bill, we're assuming Joerg's check is in the mail, right?
