You probably wouldn't actually need to cut the nozzle of the balloon' date=' cept if you want style points.

 

The paper clips would provide ballast. Gravity would pull on them more than on the rest of the project, so the balloon wouldn't spin around the straw, just force the air out.

 

As long as you get the tape centered, I don't think it would point downward.

 

Maybe a hobby shop like Hobby Works or someplace for an airplane?[/quote']

Where and why would you put the paper clips?

 

@Phi: Where would you cut it, if the balloon is going to the right? To the right of the knot? Would that reaaally work? @_@

After checking out the online stuff' date=' my $2 idea is more like $6-$7. Personally, I like Anjruu's idea of the straw glued to the balloon. Use a wood glue like Elmer's since a superglue may eat a hole in the latex. You'd need to cut a slot along the SIDE of the straw so it can be attached to the fishing line. Use scissors to dramatically snip the tied end of the balloon to get you going.

 

Here's the kicker: go have a burger and soda at Red Robin or some other place that gives balloons to the kids. You talk them out of an unfilled balloon, make sure to grab the straw from your soda and you tell the teacher your vehicle cost you nada, zip, bupkis. And your vehicle will have a sponsor's name on the side.[/quote']

 

Why would I cut one end of the balloon? I don't get it..

 

You mean, (if the balloon is being held upright) right above the knot thing to let all the air out? Wouldn't that...not work?

 

How would I tie the balloon to the straw? It'd have to hang a bit. Wouldn't the balloon be tilted downward because of the weight?

 

Where would I tape the clips to?

 

Phi/anyone: Could you make a diagram on Paint telling me where and how to put everything to make it go? 'Cause I seriously don't get how you'd do this.

 

By the way, I went to a nearby store which everyone in my class said would have the airplanes. No. nothing. My brother never even heard of them and he worked at Kmart for a whiiile..

I live in Jersey and ya, there's a Walgreens near here. Thanks guys. You're too nice!

Buy a $2 rubberband powered balsa-wood airplane. Attach the landing gear assembly upside down, snip off the wheels and bend the end of the gear wire into a small circle (this is where the fishing line will run through). You could attach the other leg of the wire near the tail for stability with the same wire circle. Wind up the propeller and let it go. If it's stable enough on the wire you may not need the wings or tail either.

Yea the teacher mentioned one of those. But where can I buy them? I never seem em anywhere..this is what I'll prob'y use...so please, where can I get one?

Go to radio shack' date=' buy a $9.99 motor. It probably weights about 100 grams. Get a cheap plastic fan blade, glue it to the motor, and hook up a cell phone battery. Get a straw, and attach this whole dealie to the straw.

 

Or get a straw and a balloon. Blow it up, and attach it to the straw, and let it loose. Simpler, cheaper, lighter.[/quote']

How would you attach the cell phone battery to that? where? I'm a dumb kid, help me out. i'm gonna go look at a picture of a standard electric motor righ' now.

Electric motor and a fan could be used to propell it.

Ok, but would a fan really be powerful enough? It has to small and light dude, so you'd have to use one of those handheld fans and stuff. Would that be strong enough? Could anything that I wouldn't have to go out and buy be used? Or at least something easy to find..

I need to do this project too..

We can't hit it or any bs like that. It should be lightweight. I wanna make it hang from the line. So, you can use pumps for rockets and stuff like that. About the electric motor: Where could you buy one of those? Any major stores carry them? Could you also give me another simpler way to do this?

Psquared, if anyone responds with a simpler way, I called it!! hah xD
