Ball that need to bounces indefinitely

I’m trying to make a ball that bounces indefinitely without losing power. I set it’s elasticity to 1 and friction to 0 but it still lose power. I saw somewhere that the part it bounce against also need to have elasticity 1 but I can’t do that because other things will hit them. I’m searching for another way but I don’t know how

its actually bouncing with friction try putting its mass property to 0

Can’t change the mass property. Can indirectly change the mass with the Density property but it can only go as low as 0.01
