I have to say that I heard about this idea from a good friend of mine who was working in an Infant room at the time and I just thought it was such a simple activity. Whenever her centre or staff received any goods that was wrapped in bubble wrap, they would tape it to the floor. Children found this so interesting and were walking over it all day. If children are allowed to take their shoes off, this is great for sensory exploration.
Other things you could use are cellophane, wrapping paper and pieces of material. Obviously you need to ensure that these are taped firmly to the ground and children are supervised. I would recommend packing tape.
