-cup/glass of water filled near the top (but not full!)
-a piece of cardboard or a card
Can we pretend that... LOL jk
So the mini-project I decided to do was to fill a cup with water, put a card on the bottom, and turn the cup upside down, WITHOUT the water splashing out.
How does this magic water and cup work? (Science)
If done correctly, the paper should stick to the cup, with the water still inside, because the air pressure from outside the cup is greater than the pressure inside.
