RRRRRRRRRROCKETS!

Ok, here is a fairly simple toy that is easy to build and fun for kids of all ages.

 

AIR ROCKETS!

 

What you'll need:

 

(1) 2 liter bottle

 

About 4 ft of 1/2 PVC pipe, cut into the following lengths:

(3pc) 12", (1) 10" and (1) 2"

 

Other PVC parts:

(1) 1/2" Cross, (2) 1/2" Caps, (1) 1/2" 45° angle and (1) 3/4" - 1/2" Slip hose to pipe connector

 

 

Some EVA craft foam - try to get the thicker variety, about 1/8" thick

Electrical tape

Poly report covers - check the dollar stores or an office supply

Glue

(2) 4"x2" thin plastic - plastic wrap or cut the pieces out of the shopping bag from buying all the stuff.

Now to assemble the launcher:

 

  1. Place a cap on one end of two of the 12" pieces
  2. Fold one of the 4x2 pieces of plastic in half and wrap around the other end of a piece from step 1 and insert into the 1/2" Cross. Repeat for the opposite side of the Cross
  3. Insert the 2" into one end of the Cross and attach the 45deg
  4. Insert the 10" piece into the other end of the 45deg
  5. Insert the remaining 12" piece into the remaining hole of the 1/2" Cross
  6. Slip the hose connector to the other end of the piece from step 5.

Now to make the rocket:

  1. Cut a 9x5 piece of poly.
  2. Apply a piece of electrical tape to one 9" side
  3. Wrap this around a piece of the PVC to form a tubeIMG_20120511_120029.jpg
  4. Once the tube is secured by the tape, pinch one end and round off the cornersIMG_20120511_120210.jpg
  5. Seal this end shut with electrical tapeIMG_20120511_133420.jpg
  6. Now take the EVA foam sheet and cut a strip about 1-1/2" wide.
  7. Cut some rectangles from the 1-1/2 wide strip and then cut them in half along the diagonalIMG_20120511_120441.jpg
  8. Apply glue to a long edge and place on the tube. I used three per rocketIMG_20120511_133437.jpg
  9. Let the glue dry
  10. Place rocket over the end of the 10" piece of PVC
  11. Have 3yo STOMP on the 2 liter bottle
  12. Witness fun and excitement

(sorry - didn't take the time to rotate the video)

 

With a good stomp, an older child or adult can shoot the rocket 25 yds or more...

Hey Paul,

 

That looks awesome! Thanks for adding this on here and putting together a video too no less = )

 

This would be an awesome thing to keep my brother and sister entertained during the summer, thanks for the idea!~

Hey there Paul,

 

Thanks for the great weekend project. Nice and simple. Great step by step pictures. Anybody could build this project.

 

I could see my family and I making it into a game. Seeing that were all very competitive. Like who can make it go the furthest or making different size circles on the ground at all different distances that are worth different points.

 

We love games like this that are simple, portable and easy to play for the entire family. We take them out to the desert with us when we go riding.

 

I have a couple that I'll have to do a post on to share with the community. I did one already on the marshmallow shooter. We have a lot of fun with them.

 

I will definitely have to make one of these real soon. I'll post some pictures once I complete it. 

 

Thanks again for sharing.

Wow Paul!

 

So simple but such a fun project!

 

I'm glad you used my favorite glue we sell in our stores, the Clear Projects Adhesive by Liquid Nails. I've used that on all sorts of things around my place to fix and attach stuff...I may just do a post about it lol.

Looks like the rocket most definitely passed the oh-so-tough kid test!

I had the glue around and it is safe to use with the foam (won't melt it). If I didn't have that, I probably would have just used some silicone caulking. It's basically the same stuff. Since caulking has to stick to the surfaces to which it is applied, caulking is glue.

 

As an alternative to the 3/4" to 1/2" slip hose to pipe connector if you can't find one, take a 2-liter bottle with you to the store. Just look for a reducer that will fit over the threaded opening of the bottle and connect to the 1/2" pipe. Then just use some of the electrical tape or duct tape to fasten it on.

 

You can also adapt shecandoit's Marshmallow Cannon to fire rockets of the same design.

UPDATE: After completely demolishing a 2-liter bottle at the family picnic, we attached a new one. Our dart distances were approaching 50 yards and about 30 feet high at the apex of it's flight.

 

The Marshmallow Cannon now has me thinking...
