1st experiment I used:
heavy cardboard, sandpaper, aluminum foil and light cardboard. The foil slid down first, next was the light cardboard, next was the heavy cardboard and the sandpaper did not move!
2nd experiment I used:
small bottlecap, medium bottle cap, lego and squishy toy. The lego went first, then the small bottle cap, then the medium bottle cap and the squishy did not move.
3rd experiment I used:
sandpaper, rubber duck, squishy toy, bottle cap and heavy cardboard
The bottle cap went first, then the duck, the heavy cardboard next and the sandpaper and squishy toy did not move until I pulled the board straight up!!
