You will need 5 sticks that are are 4-6 feet long with a diameter of 1-2 inches. I am using 4 foot long sticks. The 2 shorter sticks you need will be 2-3 feet long also with a diameter of 1-2 inches. I am using 2 foot long sticks. You will need all of the items shown in the picture. You will also need something that will make a hole about 1/2 an inch wide, such as a drill. Another thing you will need is approximately 60 inches of elastic band that has a diameter of about a half of an inch. Another thing you will need is some sort of bowl of cup to use as the holder for the item you will launch. Pictures of these items come later in this instructable.
