Get ready

Same low ramp and ball, stiff cardboard angled bumper and soft cloth bumper; identical target.

Safety

Roll a soft ball on a clear floor away from stairs, doors and people; never throw it. Short strings stay on the table, never around a body.
Only a grown-up uses scissors or cuts cardboard. Keep small pieces out of mouths; use large cards.
