Laura floats a brussels sprout
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Laura initally tried to blow the brussels sprout with the leaf blower, before filling a bucket with water and putting the brussels sprout in it so it would float. She then lowered the bucket down from the balcony with a rope, tying it to the balcony's bannister where it was left to hang, causing the brussels sprout to remain floating. She floated the brussels sprout down from the balcony for 74 days, three hours and 48 minutes, receiving 5 points.
