some church friends (one of whom is also a preschool dad) put in a new hot water heater for our church/preschool. the sturdy box was left for us. we bring all the blankets and pillows from the whole classroom in it. we reinforce it with colored tape. we cover the opening with fabric. we pound on the top and make it sound like thunder. we hide in there and are really quiet so that a teacher has to look to find us. and one day, a couple of friends got the box to roll!
enjoy the movie:
