Rocket Science Fair Projects

I test this type of liquid rocket will fly very fast (im going to put water in one .. and maybe soda or milk in the other)


But how can I make a rocket?

Do you think this is a good science fair project for a seventh grader

make a mentos coke rocket
Just take a nail and make it hot (I suggest a long nail, but not very long, maybe 2 1 / 2 inches?)
then poke it through a plug
Now you have a hole

then stabbed three or four mentos on the nail
tie a string on the nail
then quickly screw the bottle cap to a Diet Coke
(I've only tried diet coke, so I do not know if the coke regular work)
shake
then pull the nail
he can not fly like rockets NASA perfectly done, but im sure it will be pretty amazing

I made a water rocket physics and the best I can say is use a two leter bottle and find a way to get akaselzer (the drug antindigestion sparkle, I was not sure of the spelling). your nose cone to make it as long and thin as possible. and make your rocket as light as possible while it takes is a nose cone and wings three regularly spaced, think more of the fin shape and not the rocket plane. Hope this helps.

You will find a way to put pressure on the rocket.

You want to put pressure on everyone the same amount, so that the liquid is ejected at the same speed.

You will have created conditions apply to the experience.
And get valid data.

Build a device that can hold a bottle of 2 L of soda upside down.
Make it a clip to hold the neck safely. able to maintain pressure.

Use the same amount of liquid mass "reactive".

Having an air connection in the device to make the propellant charge.

Load each rocket with the same amount of "fuel".

Then perform the experiment.

check store science site I did something like this in the fifth grade my teacher actually called the airport to tell people that there would be rockets into the air just to use the and water pumps

idk

Hear what you do. You get two leter bottle (empty), tin foil and toilet bowl cleaner TNT. Place the bowl clean roof first. Then place the tin foil in quickly and turn the cap and IMMEDIATELY start hut now. It is so cool.
