Bill Gates is the latest famous person to take part in the ALS Ice Bucket Challenge. But Gates actually went above and beyond the call of duty by doing some fun.

Gates pretends he is determined to improve how the water is delivered onto his head, so he draws up plans for a mechanism to save him having to lift the bucket above his head.

It works too, although some pedants online have pointed out it’s a really shoddy invention. Like Gates was serious or something.

Bill Gates is a billionaire philanthropist who found fame and fortune by founding Microsoft and creating the Windows operating system. But he still has a sense of humor, which is really nice to see.
