So ... you need/want a mini percussion shaker and don't want to spend $7-8 on an egg ($2 for a pair on Amazon)? You tried making your own egg using parts from your little Brother's Easter basket, but ended up covering the front row in rice when it came apart? Well my Friend, I have a solution for you.
1 6oz metal can ($0.50 at the Supermarket)
Side cutting can opener. These are also called "safety" or "Smooth Touch" can openers.
Step 1: Empty, Fill, Glue
Consume or save the contents of the can (I used mine in Chili).
Wash out the can (Removal of label is optional).
Fill can with desried amount of rice.
Glue lid back onto can.
You now have a Fixed Mini Percussion Shaker.
Step 2: Make an Adjustable Version
Well ok little buddy! Grab yourself a nut and bolt (which work together obviously), a small scrap of wood, and some epoxy.
Step 3: Drill the Lid
Step 4: Drill the Wood
Length doesn't matter because we are cutting it to fit inside the can.
Drill a hole just large enough and deep enough for the nut.
Switch to a smaller bit, which is the size of your bolt, and drill the rest of the way through.
Step 5: Layout the Size and Shape of the Wood
Step 6: Shape the Wood to Fit Inside the Can
I snuck up on the line and kept testing the fit. Worst case scenario, you have to make a new piece.
Step 7: Epoxy Time
Glue the nut into the larger hole in the wood.
Glue the wood into the can. Make sure you recess (I wish my day job had recess) it enough for the lid to fit back on flush.
Clean up any excess epoxy that might hinder the lid fitting on once cured.
Step 8: Fill and Cap
Put the lid on the top.
Tighten the screw.
Don't want to have to use a screwdriver every time? Use a slotted head screw wide enough to open with a dime. Another option would be to use a thumb screw.
