The Self-Filling Cup uses scientific principles to partially refill after all liquid has been poured out. This model is perfect for magic shows and lessons on air pressure. To perform the demonstration, start by completely filling the cup with liquid. Next, cover the hole near the brim with a finger and pour out the visible liquid. Refill the cup by uncovering the hole.
For a more complete explanation behind the science of the Self-Filling Cup, watch "2D Water Magic" on YouTube by Steve Mould (Link below). https://www.youtube.com/watch?v=HiDHFg68BR0
