These materials are all easy to get. The plastic tub and lid are recycled from the grocery store, or you ask in the store for an empty one, they sell for about 25 cents, but if you explain why you need it you will get it free, most likely! Any one or two elastics will do, they need to be long enough to span the length of the tub and a little more. You need also a medicine cup, you can get it at any pharmacy, free if you ask nicely. The wooden tooth pick or match stick at the bottom is needed to stop the elastic from turning, the steel washers are used to lower the friction, or drag, so your Moto Magic 2 will run better. The larger stick is a used shish-kebab scewer, or any larger but light stick or rod about 25-30 cm long.
