Amazing displays of ignorance
Sandettie Light Vessel Automatic tells us: "My dad's friend told us there's no such thing as gravity - it's just the weight of air holding us down". Tell us of times you've been floored by abject stupidity. "Whenever I read the Daily Express" is not a valid answer.

This reminds me
of an experiment Richard Feynman allegedly did as an undergrad.
The question was, a sprinkler (think S shaped) rotates clockwise due to the water coming out at a certain angle etc etc, so what happens is you use the sprinkler to suck up water in a submerged situation: which way will it spin. As a theoretical exercise they would argue about it one and the other, and come up with very convincing explanations why it would rotate anticlockwise, and equally plausible explanations why it would spin clockwise.
So one day Feynman does the experiment. He sticks an improvise sprinkler into a huge vat of water, turns on the pump, and half destroys a lab in the process.
And the answer by experiment? It doesn't spin at all, because it is just a bent pipe sucking up water.
