Many instructors provide a penalty box. A high sticking infraction during a game will require the student to be put into the penalty box for two to three minutes. One instructor supplies students with a foam hockey stick if they have to many penalties. High sticking can cause the puck to fly into the air causing injury. Because the results of high sticking and other dangerous shots, safe hockey pucks are a necessity in floor hockey.
Some instructors use hard foam balls.
The hard foam balls sting when they make contact with a student, but not nearly as much as a hard puck would. Another instructor substituted beanbags for plastic pucks. They work extremely well on the gym floor, and they never leave the ground. One instructor noted that he uses a hockey puck that floats on a cushion of air make by the Toy Company Mattel. Another class uses a wiffle ball that has pieces of a tennis ball inside it.
