Another toughie!! Talk about schoolwork. This is an activity badge that few Webelos achieve. Here are a few suggestions. Good

luck!

Inquire of your PTA or Principal if there are some service projects that the scouts can do. Upkeep of a flower garden,

room setup for a PTA meeting, board are possibilities.

and preparation of a bulletin

Visit a public library and see how it works. All scouts should apply for a library card if they don't already have one.

Ask a local school administrator to visit and explain how the school system operates. Also explain why bond issues are needed. You could probably do this yourself in a discussion group.

i

Perform a book drive. Collect books for the school's library and your public library.

Invite a person from another country to come to a meeting

Create a diploma or document. To acquire a brown, aged look, soak typewriter paper in a pan of coffee for an hour

and discuss how schools are run in their home country.

or two.

Blot and let dry.

The paper should look sepia or

light brown in color. Obtain several feathers at a craft store and by cutting the end off at an angle, you create a quill pen. Use the quill pen and ink to create the document. If you cannot find feathers, a twig about the thickness of a pencil can be sharpened and used as a pen.

If you take the time to look at a variety of structures, you will notice one thing that most of them have in common, especially taller ones. Most structures are wider al the bottom than they

are at the top. One reason for this is that a tall building has a lot more weight which must be supported. Also, a wider base ensures that a structure's center of gravity (the imaginary point within a structure from which it would be equally balanced in

HAVE A

TLE ROCKET BLAST!

The sophistication of today's toys is

nothing short of amazing ... but it's dif ficult, sometimes, to justify the «xpense of such playthings. By using just a little old-fashioned ingenuity instead of mon ey, though, you can keep your budget intact and provide the youngsters in

your fold with countless hours of safe entertainment.

For example, if you can dig up a cou ple of two-liter plastic soft drink bottles, a bicycle tire pump, some pine scraps, string, a plastic dry-cleaning bag, hard ware odds and ends, and perhaps $2.00

worth of plumbing fittings, you can put together the water-powered skyrocket that you see here ... a truly impressive "extraterrestrial" traveler that's guaran

teed to put pizazz into any family's day!

The two-stage missile uses, believe it or not, nothing more than compressed air and water to achieve altitudes of well over 100 feet... and then, at that

point—when the "booster" has expend ed its fuel supply—the first stage sep arates and deploys its payload: a nose cone that, with the help of a small para chute, floats safely back to earth. As you've probably guessed, one of the soda bottles serves as the propul sion unit... a sensible choice, since the

jug's polyethylene skin is capable of •

''••I

withstanding nearly 200 pounds per square inch of water pressure before bursting. (Of course, you'll only be feed ing it a fraction of that amount, so there'll be plenty of launchings available from a container before it self-destructs.) To prepare the first stage, you need only to paint or tape the body to simulate one of the "big jobs" ... but do remember to

leave an untouched strip the length of the bottle so you'll be able to see how much H,0 "fuel" it contains.

The nose cone, on the other hand, is made from the neck and upper portion of the second container... just cut around the bottle at the point where the taper meets the straight midsection. Next, a

simple parachute can be fabricated by cutting a 2'-diameter circle of light weight plastic from the dry-cleaning bag and attaching—with small tabs of adhe sive tape—eight 18" pieces of string spaced equally around the chute's cir cumference ... the free ends of the cords are then gathered together and tied to a hole in the side of the cone.

Finally, the threaded part of the neck can be adorned with a piece of foam rub ber cut to a pointed shape.

The launching platform is just a 1/2* X

12" hunk of plywood—trimmed to form an octagon—upon which is fastened, us ing five countersunk No. 8X1-1/2" wood .-»;■•.

screws, a control shack consisting of

one 6"-long 2X4 braced perpendicularly with another that's 4" in length (both

members should be beveled and shaped to approximate the silhouette of a real blockhouse). Three 3/4" X 3/4" X 4" - wood strips are similarly screwed to the bottom of the base (as shown in the dia

gram) to serve as legs ... and as a final measure, a 3/8" hole is bored through the platform and the leg beneath it, op posite the control shack, to accommo

date an anchoring nail or gutter spike. The plumbing fittings function as both a support for the rocket and a means

of delivering the pressure necessary to

launch it. Assemble them by first thread ing the inside of the ribbed end of a 1/2" ABS female pipe-to-barb 90* elbow with a 3/8" pipe tap. Then screw a 3/8" brass hose barb into that opening, and fit the elbow's other end with a 2" nipple of Schedule 40 1/2" PVC pipe. Fasten the air-supply hose—a 12-foot piece of 3/8"

plastic tubing fitted at one end with the valve stem from an old inner tube—as in dicated in the illustration, and then, after drilling a 1-1/8" hole in the center of the launching pad, mount the plastic elbow

to the underside of the plywood with a pair of 1/2" copper-pipe clamps and No.

4X1/2" wood screws. (Make sure the PVC pipe nipple protrudes squarely from the pad's central hole.) Now force a garden hose gasket over that nozzle support and temporarily slip the bottle onto the nipple. Carefully mark a line on the 2 X 4 block directly

across from the collar molded into the container's neck, and then bore a pair

of 1/8" parallel holes at this line and far enough apart to equal the outside diam eter of the neck itself, which should be about 1-1/8 inches. (If you must remove the control shack blocks from the plat form in order to align these holes prop erly, by all means do so.) Finish the release mechanism by

bending a 10" piece of 1/8' welding rod into a "U" shape (to match the holes), slipping the wire prongs through the block, and bending their tips outward so they'll slide over the neck collar easily. A 12' length of cord equipped with a dowel handle can then be tied to the welding rod to serve as a remote-control launching "trigger".

To protect the wooden platform from the effects of necessarily wet blastoffs, you'll probably want to paint it in the color scheme of your choice. As soon

as it's dried, you'll be ready to try a first launch.

Select a location free of trees and overhead wires, and anchor the board to the ground with a spike. Prior to launch

ing, it'd be a good idea to coat the PVC nipple with plumber's grease. Then you

can fill the craft's propulsion stage

about three-fifths of the way up with wa ter, nimbly invert the booster so it rests atop the nipple (you'll lose a little, but not much, liquid fuel) and shove and lock the welding rod clip over the bot tle's neck collar, forcing the container down against the hose gasket as you do so.

At this point, with "T minus zero" rap

idly approaching, prepare the payload for successful reentry by lightly folding and packing the parachute and its cords (you didn't get them all wet, did you?) into the cone and placing that cap over the

booster's blunt nose. Then, as one per

son plugs the air valve into the bike

pump and proceeds to build up pressure,

while another stands at the ready with release cord taut, a third (and, most like ly, a fourth and fifth, etc.) can be watch ing the platform for signs of pressure-in duced leakage (everyone should be standing well back from the rocket...

make no mistake, this toy is powerful). When the seepage occurs—at about 40 to 50 PSl—the crew's excited cries will signal the launch technician to yank the 3 release ... and w-h-o-o-o-s-h ... you all | can enjoy the thrill of a scaled-down t
