Ever bored in class? All you need is an old Squeaking pet toy and a pen!
Step 1: Find a Squeaker
This is probably the hard part of this project so after this we're gonna flow. Find one of these squeakers! They're in pet toys or anything that squeaks!
Step 2: Take the Squeaking Part Out
Pliers aren't necessary, it might damage it. Use your fingernail and slip the squeak piece out of the air chamber
Step 3: Take Then End Cap Off of the Pen
Use pliers, they might be pretty tight
Step 4: Put the Squeaker in the End!
It should be a perfect fit
Step 5: Poke Some Holes
Get a sharp thin needle or drill and poke some holes in the side of the pen, or else air won't pass through it
