Repeat this procedure for the other pipes. Suspend the small disc in the centre of the grouping of pipes about halfway down the length of the shortest pipe. The chimes are now assembled. Drill two holes near the edge on opposite sides of the large disc. Use these holes to hang the chimes.
Wind chimes have an aesthetic use.
By discussing devices which make use of the force of the wind, the students' awareness of energy conversion can be raised. Here the motion energy of the wind is converted to sound energy. Find or develop some activities to demonstrate that air occupies space. Use bags of thick plastic, such as freezer bags, or the bags in which some newspapers are delivered. Then try to stuff the bag into the jar without breaking the seal.
