A bottle rocket is a small model of a skyrocket. They are special types of rockets that are designed to soar into the sky rapidly before it explodes. They are made up of a rocket engine that is attached to a stabilizing stick. It gained the name “bottle rocket” because of the custom to put it in a bottle where the rocket engine is lit and the bottle guides the object to ascend in the sky. There are various versions of bottle rockets: the fireworks ones and the plain types designed for just flying.
HOW BOTTLE ROCKETS OPERATE
The fireworks bottle rocket has a tube filled with a kind of explosive material. When it is ignited, the explosion that is set off pushes the rocket into the air. Other explosions Designer bottles uk are set off resulting in colourful fireworks. Some are designed to make a screeching sound while they fly through the air.
It is certainly great encounter to design a bottle rocket by yourself and watch it shoot of into the sky. Here are the instructions to make a straightforward rocket made only for flying; not a complicated type with fireworks.
2 liter soda bottle
2 x 4 piece of wood
1/8″ thick steel
2 extra long nails
#4 test tube stopper
1.Remove the label and the ring around the neck of the bottle, then use paint thinner to eliminate the glue from the bottle.
2.Cut four fins out of the balsawood with handsaw and smooth them with sandpaper.
3.Fasten the fins to the bottle using rubber cement.
4.Use scissors to cut a nose cone from the manila folder then use rubber cement to attach it at the top of the bottle.
TO MAKE THE LAUNCH PAD
1. Using the handsaw, cut two 6″ blocks from the 2 x 4 wood.
2. Cut another piece measuring 1 1/2 feet long, 6″ wide and 1/2″ thick.
3. Use the screwdriver and screws to fasten the two 6″ blocks to the long piece of wood to form a table-shaped object which is the launch pad.
4. Screw the junction box in the centre of the object.
5. Drill a hole through the junction box and the launch pad then place a test tube stopper through it.
6. Using scissors cut some copper tubing and place it inside the test tube stopper.
7. Use hose clamp and affix the tube to the air pump.
8. Bend a piece of steel in the shape of a ‘U’. Slide it into the holes drilled in the junction box and tie a piece of string to it.
9. Drill a hole in each side of the launch pad. Push a nail through each hole and into the ground to secure the launch pad.
1. Throw 2-3 cups of water inside the bottle and attach it to the launch pad by placing the pin over the bottle neck.
2. Switch on the air pump so the rocket can be pressurized.
