How much do you need to vomit in order to levitate?
That's the kind of thing we've all thought about, right? Minute Physics investigated!
You'd have to vomit around 5 gallons (nearly 20 litres!) of milk
per second in order to levitate. That's a lot of milk.
Or you could use special super-dense milk, with lead or mercury
in it. Planet Science doesn't recommend that - lead and mercury are
poisonous!
