What makes us keep our feet on the ground?
It's gravity.
Teacher asked us whether a bottle would float or drop if she let go of it.
We had to guess the answer.
What do you think?
We guessed that gravity would pull the bottle to the floor.
Next teacher filled one bottle with water and left the other one empty.
Now when you drop the two bottles which falls the fastest?
Watch the videos below and see are you right!
Did you guess correctly that they both hit the ground at the same time?
Surprising isn't it.
You should try this at home.
