Build a film Canister rocket

You will need!

- One empty 35mm plastic film canister and lid. These are getting harder to find, but stores that develop film should have some. (The white canisters work much better than the black ones do.)

- One fizzing antacid tablet (such as Alka-Seltzer – Get this from your parents)

- Water

- Safety goggles

What to do?

Put on those safety goggles and head outside – no really, when this works, that film canister really flies! If you want to try the indoor version, do not turn the canister upside down in step 5.

Break the antacid tablet in half.

Remove the lid from the film canister and put a teaspoon (5 ml) of water into the canister.

Do the next 2 steps quickly

Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.)

Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 meters.

About 10 seconds later, you will hear a POP! and the film canister will launch into the air!

Caution: If it does not launch, wait at least 30 second before examining the canister. Usually the cap is not on tight enough and the build up of gas leaked out.

How does it work?

There’s nothing like a little rocket science to add some excitement to the day. When you add the water it starts to dissolve the alka-seltzer tablet. This creates a gas call carbon dioxide. As the carbon dioxide is being released, it creates pressure inside the film canister. The more gas that is made, the more pressure builds up until the cap it blasted down and the rocket is blasted up. This system of thrust is how a real rocket works whether it is in outer space or here in the earth’s atmosphere. Of course, real rockets use rocket fuel. You can experiment controlling the rocket’s path by adding fins and a nose cone that you can make out of paper.

The Difference Between Being Intelligent And Being Wise

Intelligent : • wise, cunning, capable of thinking and reason Wisdom: • The state of being wise • Ability to use knowledge and / or experience wisely • Able to determine what is wise against what is unwise • A saying, a philosophy or other advice considered wise In Short: An intelligent man has a whole sea of knowledge and knows every fact. On the other hand, a wise man does not have all the knowledge that an intelligent man has, but he has the brain to know when to use knowledge. I have seen a lot of smart people make really stupid decisions. I was one of those people! The information I had before and after these decisions has not changed. But with every wrong decision, if I was willing to learn, my level of wisdom changed. The main difference is that: A smart or intelligent person knows how to solve any problem. A wise person knows how to avoid this problem. Knowledge makes a person intelligent. Experience makes a person wise.
