About this deal

Place a layer of insulation material at the bottom of the can. Perlite, vermiculite, or ceramic fiber can be used for insulation. The insulation should be about 1 inch deep, and should cover the bottom of the can. This insulation layer will help to retain heat and improve the stove's efficiency. Step 5: Install the sheet metal tube So, you’ve fitted the small tins together to make an L shape inside the larger can and this shape sits in the centre of the larger tin with about 3cm of space underneath.

I cut a circle of plastic bag about 10 inches in diameter, and put 8 pieces of duct tape around the circumference of the circle. These were reinforcement for the 8 slits I cut around the circle for the parachute lines. I cut out 8 pieces of line, about a foot and a half long. You can really use any sort of thread-like material. I was in a pinch so I used dental floss! I tied the strands through the slits with a square knot, then tied all 8 lines together. After testing the parachute to make sure it worked, I folded it up and stuffed it inside the body tube. You'll want to use some recovery wadding, inflammable paper, to prevent the parachute and other internals from burning up. If you don't want to buy some, you can make your own with this Instructable. Stuff the wadding in first, then the parachute. By entering this competition, an entrant is indicating his/her agreement to be bound by these terms and conditions. Also, it is much easier to transport than a regular oven, making it perfect for camping or hiking trips. Use the compass to mark out the 4" radius circle onto another manila folder. Cut it out, then fold the circle in half. Cutting along the fold, you'll be left with two semicircles. Cut a small notch in the middle of the straight side of each semicircle. These notches help to form the sharp point of the cone.Heat a tablespoon of the oil and fry your sausages. When browned, remove from the pan, cut into chunks and set aside. An ash pan catches loose ash and prevents it from clogging theairflow. It acts as a heat shield and prevents your stove from scorching the ground. Vent holes near the top of the burn chamber allow preheated oxygen to fuel the flame resulting in a more complete combustion and a hotter fire with less smoke. Now when you blow up a balloon, the air makes the balloon stretch bigger and bigger. But the little film canister doesn't stretch and all this gas has to go somewhere! This can make it difficult to regulate the temperature of the stove, and it can also make it difficult to cook food evenly.

The final piece you need is to create a line so you don't lose your nose cone, and a parachute for recovery.

Blasting Off

Finally, use a piece of line, maybe about 1 foot long, to attach the nose cone to the inside of the body tube. This is so that when the ejection charge goes off, it won't blow your nose cone away; it'll still be attached by the line. Heat the other tablespoon of oil and add the garlic and onions. Fry for a few minutes, until the onions start to soften. And so from the thousands, one remained — the design that could not only carry out the mission to Mars, but could do so most safely, affordably and sustainably. When the fizzy tablet is placed in water, many little bubbles of gas escape. The bubbles go up, instead of down, because they weigh less than water. When the bubbles get to the surface of the water, they break open. All that gas that has escaped from the bubbles pushes on the sides of the canister. If your pupils have been learning about astronauts, then you can get them to compile their knowledge in one handy place with this Astronauts Mind Map. Alternatively, it would be a great way for kids to brainstorm right at the start of a topic.
