DIY - How to Make an Underwater Microphone (Hydrophone)!

The fish says, “nice work bud, now I can start vlogging about my life in the fish tank!”

Construct a inexpensive hydrophone out of things laying around your house.

I decided to put up this instructable because (to my surprise) no one has a hydrophone instructable up yet. I made mine using a mixture of other people’s hydrophone creations that I found through a google search and a bit of ingenuity.

Here’s the parts that I used but it should be fairly easy to adapt whatever similar items that you can find.

computer microphone

plastic wrap

vegetable oil

solder

knife or scissors

bottle
