Water crazes

Not so long ago we had the ice bucket challenge, which led otherwise normal people to have cold water poured over them for charity.

This followed tombstoning, where people stepped off ever higher cliffs into the sea.

Now it’s bottle flipping. You flip a nearly empty bottle of water into the air and see how many times it takes to land it upright.

In all cases, it doesn’t count if it hasn’t been filmed and put on the internet.

Bottle flipping has become so popular that a school has had to ban it.
