My water machine

Today we had to design and create a machine that allows user to successfully complete there underwater observations. It needs users to see clearly underwater, while standing in the stream, Also it must meet all 6 criteria which is:
1. It must allow user to see clearly underwater.
2. It must not require user to go underwater.
3. Must be portable and easy to lift.
4. Must not disturb the river bed.
5. Must be handheld.
6. Must be made out of waterproof materials.
It was really fun to create.
