Thumbs up Orbit Speed

You're correct, I didn't think of that, that's why I ask to get objective views and more ideas. :D So, refresh my memory, what exactly determines the speed of the electrons? (I realize that we are...

Post Part B, it wouldn't let me type anymore.

The other side of this example would be the sequel "Honey, I Blew Up the Kid", in which Wayn Salynzski makes his 2 year old up to 200 feet tall! The same principles apply. If the little tyke...

Post This should keep us up all night.

In Disney's "Honey I Shrunk the Kids", Wayn Salynzski, played by Rick Moranis, creates a machine that can make things bigger and smaller. He quotes in the film that the way he does it is by...

Thumbs up Agreed

Michael is correct. Regardless of where the rocket is located, in air, in the vacuum of space, or even UNDER WATER, the "fire" coming from the rocket engine does NOT push on the surrounding...

Exclamation Wow

That sounds really complex for your grade level. If it's not too late you can Instant Message me, or write me a private message giving some more details. It sounds like you would be building an...

Exclamation Low Orbit

Unfortunately, the only way to get a model rocket into low orbit is to have an O class motor, even as high as an R class. To use these engines, you must be a certain age(18 or 21 I think) and be...

Thumbs up Further Detail

Icstars has the right idea, spot on. You want to control the payload weight very precisely. The size needed for the actual chute is determined by the weight of the payload, and the material used. ...

Lightbulb Tornado Machine

Although it will not look exactly like a hurricane, a tornado machine demonstrates the same priciples for vortex weather patterns.

Here is a link to a tornado machine that some men built for a...

Do what you like.

Well, at least you have time. LOL

If the science fair or project does not have a "theme", and you are free to do what you like, then do so. If you like science, then simply choose your favorite...

Lightbulb Best Physics Project

Usually the best physics project that I keep seeing getting high marks, are built-from-scratch trebuchets. They are like catapults, but they work differently. You can REALLY impress the judges if...

Thumbs up Solar Powered Car

You can buy solar panels at hobby and science stores. They come with a few solar cells, and a pair of wires. Some even come with motors. The solar panel creates an electrical current. I can't...

Thumbs down True Rocket Fuel

Baking soda and vinager are not a sufficient propellant. The chemical reaction does not give off enough energy fast enough to propell a rocket. You can barely explode a soda bottle with baking soda...
