Q

What do you think will happen to the oranges if you squeeze and throw them?

A

By squeezing the oranges, you’ll release the juice inside.

Oranges will likely break apart or bruise when thrown, depending on how hard they are squeezed and how forcefully they are thrown. If they are already weakened by squeezing, the skin might split or the orange could burst on impact, making a mess. If the orange is mostly intact, it could just get bruised or squashed.
