This can be any form of cans such as paint, coffee, and food cans. Try reaching out to the community and ask for can donations.
Please let them know that the cans will be upcycled instead of being tossed into the bin.
Again, look for unused paint in the community. Might also want to consider a coat of varnish to protect the paint.
This step ensures that the can drains and no collect water, so you will not be dealing with soggy butts when you empty the cans!
Cut out a piece of cardboard and place it at the bottom of the can for drainage and prevents the sand in Step 5 from leaking out!
If the cardboard does not fit into the can, you can cut to the center of the cardboard and create a cone to fit into the can.
Add a thick layer of sand onto of the cardboard. This will help to extinguish the butts.
