Gravity Free Water

what goes up must go down

Ask my Question

What affect does gravity have on the cardboard and the water

Form my Hypothesis

If I fill the glass up with water,then air pressure will cause a piece of cardboard to stick to the cup

Plan my Experiment

Material

glass of water

A piece of cardboard

Steps

1.fill the glass up to the top

2.put the cardboard on top of the glass

3.tip it over and let go


Conducting my Experiment

Trial 1

18.78

It held for a long time because air pressure was pushing up on the cardboard

Trial 2

9.00

It held not as long but the air pressure still push it up

Trial 3

4.00

it held not at all it fell just like that air pressure did not help

My conclusion

I would rather us glass then a plastic cup
My hypothesis was correct the cardboard did stay
