I have a water powered rocket, how can I make luminous water for a night launch?

Answer 1

I have no idea if this would work, but water soluble glow in the dark powder is manufactured. Here is a link to a company that produces this material. They also produce paint so that you can paint your rocket.

Answer 2

A jet of water can be made to pipe light, like a fibre optic cable. You'll need to experiment to get the feel for how this works; it's easier and faster than just listening to a physics lecture on the subject. You've probably seen fountains with lights under the water which shoot up jets of sparkling water in the dark. If you've got a container with a tap and water is pouring out of the tap, If you shine a light into the container at the right angle and you've got a stream of water pouring out , when it hits the ground and breaks up into droplets, you get a sparkling display as the light escapes. So, either you fix a waterproof light source inside the rocket or, if the rocket is transparent, fix a light source on the outside, shining light into the water inside. When you've got the angle right, you should see a sparkling display where the water droplets emerge from the rocket. If you want a complete explanation of the physics, google total internal reflection.

Answer 3

Just dilute some glow in the dark paint in water and charge it up under the light for a while.

Don't let anyone think it's something it isn't even though it may seem funny to do so because you will have government agents at your house faster than you can say "It's just paint!"

Gasoline and a match?
