Instructions
Find a curved, round lid that will fit a spherical Rubbermaid trash can. The best lids are those with no grooves in them, but in a pinch curved lids with grooves will work. These curved lids are the best to use because they emulate the plastic saucers that you find in stores.
Inspect the lid for any cracks or defects. Sitting in a cracked lid may make it break further and may injure whoever is riding in it.
Rinse the lid with water to get rid of any debris or dust.
Dry the lid with a rag or cloth
Sit in the curved part of the lid and hold onto the sides while going down a snowy hill.
