Recycled Paper Bag Beach Ball

Ever want to play a game with your friends, but never seem to have a ball? Well now you can make your own in 20 min. max!

You are going to need
1. Plastic bag
2. Tape (you can use anything but I prefer duct tape)
3. Scissors
4. A mouth

Take a plastic bag, and cut the handles off.

Now tape the bottom corners to the bag. (It sticks better with duct tape.)

Fold the corners by the openings in and tape down.

Tape opening but leave a small space. Make sure there are no places for air to leak out

Now blow into it and quickly tape the hole shut. Then round it and tape it so it looks like a ball

And you have a beach ball! Or, you could fill it with water instead of air and it becomes a massive water balloon! Please comment this is my first instructables.
