1 empty tooth paste tube
Gorilla Glue (the Dries White 2x Faster one)
Drill Bits and Drill Gauge
Rocket materials -
Writing paper, copy paper, index paper (will discuss properties later)
Elmers White Glue
1. Cut the short end, closest to the flex about 1/2 inch from the flex.
2. Cut 1/4 inch slices in the cut end. You will spread these cuts after you have slid the slid the straw into the toothpaste cap. Set aside.
3. Measure the diameter of the straw using a drill gauge. In this example the straw was exactly 5.95mm or 15/64 inch. Use the appropriate drill bit to drill a hole into the center of the toothpaste cap.
4. Carefully push the sliced end of the straw through the hole until the flex meets the hole and bend the slices outward on the inside.
5. Place a bead of Gorilla Glue around the lip of the toothpaste tube and screw the cap back on. This glue will expand and secure the straw in the cap.
The example is a rocket made out of index paper. Using index paper gives the rocket more mass and the fins help it fly straighter. The best rocket for distance is a rocket made out of index paper.
A fast and dirty rocket can be made by using writing or copy paper and wrapping it around a pencil and taping it. The fins can also be made out of tape. Use your imagination.
Another rocket idea is to find a straw that is just a little larger than the straw used for the launch tube. They are out there, but it takes some effort.
Index Paper Rocket
1. Wrap a 3x5 inch piece of index paper around a pencil that is close to the same diameter as your launch tube. Again, there is a surprising range of pencil diameters so just keep your eyes open for a good match. (Tinkerers and DIYers are doing this all the time)
2. Plug one end of the rocket body. A rolled piece of paper was used in the example, but anything can be used to make a strong seal.
3. Add a nose cone and fins.
