Has no-one else attached perfectly weighted pieces of paper to the string of a helium balloon so that it floats independently around the house? (Or is that just me?)
Interestingly Helium was discovered and named by Norman Lockyer in the 1860's given that it's the second most abundant element in the universe you'd have thought some cunt would have noticed it before then.
Lockyer is mostly forgotten, but his real passion was Stonehenge and it's use as an astronomical observatory.
Norm was the sort of bloke who put the Great into Britain.
