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
