When you want to share your music with friends headphones just aren't loud enough. Fix that with cups to boost volume!
Below is a list of materials.
First you will need the cups, pen, and a speaker. Take the speaker and place it on the cup as desired and trace around it.
Now you will need to poke some guide holes on the edge of your circle with your tack. (this step will make it a lot easier to cut)
Take your knife and cut out the circle and follow the dots.(BE CAREFUL)
Make sure that the hole is not two big and not two small.
You can cut a slot for the wire if needed.
Glue in the speaker to the cup.
Make a second one.
You are done music should be much louder to share with friends
