Bottle Flip Challenge 

⭐⭐⭐ 

 Equipment: A water bottle

You will need a plastic water bottle that is filled between 1/4 to 3/4 with water. 1/3 is standard. You can play from a standing position flipping onto a table or crouching flipping onto the floor.

Players take turns to try to land a bottle flip by releasing the bottle in a spin and having it land on it's base. The amount of water, size of the bottle, height of the platform, and the presence of walls can all play a factor. You can also try "capping" it - having it land on its cap - which is much more difficult.

Try a mini-tournament. Two players face off. The players take turns flipping until one player is successful. The other player gets one last flip. If he/she lands it they continue, otherwise the winner moves on. Then two different players battle. The winner of that will face the winner of the previous match in a tournament-style bracket until you have an ultimate champion.
