One hot summer day, you and your friends go tubing at a local river.
You all are having a great time until you realize there’s a slight problem. Your inflatable is sinking!
You paddle to the shore and luckily one of your friends has a repair kit with a patch and an air pump. But after a few minutes of examining the inflatable tube, you and your friends can’t find a hole.
What should you do? You don’t want to stop tubing, but if you can’t plug the hole, the rest of the air will leak out! Is there another way to find out where the hole is?
Scroll down to find out!
There’s a solution! If you push the inflatable tube under the water, you will be able to see where the air bubbles come up. If you can see where the air bubbles come from, you can find the hole and repair it and pump more air back in! The air that is still in the inner tube will keep forcing the inner tube up to the surface and it might be too much for one person to hold down. But with the help of your friends, you can go back to tubing!
