  • It's magic! The ketchup packet is secretly loaded with pennies and when you squeeze the bottle filled with vodka, the Moon's gravity calls the packet back down to Earth.

  • what happens is that when the ketchup packet is not compressed and just stiitiing there it's less dense than water but when the water bottle's squeezed the tiny air bubble in the ketchup packet is compressed making it more dense than water and it then sinks.

  • when the bottle is squeezed the box inside fills with more water making it heavier and sink. then, when you let go of the bottle, the extra water that went into the box comes back out, and its lighter again and floats :)

    hope this helps

  • how does it do that?
