Rubber feet + plastic shooting table = sliding everywhere. Cure?

I bought a Scorpion bench rest the other day, and it's alright. I shoot off of a plastic MTM shooting table, which has bowed a bit with age. Those rubber feet are slick on that plastic surface, and between the slick feet and the bowed table, sighting can be an adventure sometimes. I'm using the foam that is sometimes in pellet cases (JSB) as a field-expedient solution to give the feet some traction, but there has to be a better way. Any ideas?
 
Like said above those work....latley I have been using silicone discs (jar grip openers) under the ACCU-TAC P-Ski Feet as they slide easily on the plastic table's surface. Got off of amazon, mine are white.

That's a good idea! I have a cap snaffler in the shape of the state of Ohio that can be donated to the cause and cut into pieces.
