Handmade Space RocketHere are a few ways to craft a space rocket:
** 1. Simple Water Rocket Creation **
1. ** Material preparation **
- A plastic bottle (a 1.5-liter soda bottle would be the best) would be the main body of the rocket.
- Paper board, used to make the tail.
- The air pump was used to inflate the rocket.
- The tape was used to fix the various parts.
- Matches or lighters (If you use solid fuel to ignite the fuel, you don't need to use water as a propellent, but it may be used in the production of other solid fuel rockets).
- Safety glasses, used to protect the eyes.
2. ** Production Steps **
- [Rocket body preparation: Choose a clean, empty plastic bottle with no residue.]
- Tailwing production: Cut out four identical triangular tailwings from cardboard and stick the tailwings evenly at the bottom of the bottle to ensure that they are symmetrical and firm.
- "Propulsion addition: Add about one-third of the bottle's total capacity of water into the plastic bottle. The water acts as a propelling agent. When the water is ejected, it can produce an upward thrust.
** 2. Making a more complicated soft landing rocket (Part of the materials and steps)**
1. ** Material preparation (Part)**
- Rocket body: 3 PET bottles (3L size, at least one is used to store soda water to withstand high pressure).
- 4x Balsa wood (200 * 25mm).
- 8x screw.
- 1x spray paint.
- 1x rubber band.
- 1x parachute (old parachute may be used, with ropes tied to each end of the cloth).
- 1x PC board (250 * 250mm).
- Electronic part: 4 cable ties, cardboard, 1 bread board, 1x accelerator (like MPU6050, including accelerator and pendulum), 2 Arduino boards (like Arduino nano and Arduino mega), 1x 3.3V voltage regulator (For example, the LM317 variable voltage regulator, if used, requires 1x resistance (390 Ohms), 1x resistance (240 Ohms), 1x servo-motor (for example, SG90), 2x NRF24L01 + module, 1x battery (for example, power bank, connection circuit board requires 1x USB-A female and male).)
- Tools: Hot melt glue gun, scissors, marker, electric iron, tweezers, measuring tape, staplers, etc.
2. ** Steps (Part-Parachute Making Illustration)**
- After calculating the radius of the bottle, measure the circumference and use the formula [r = c/(2 & pi)]. For example, when the radius is 60 mm, mark two circles with the radius of the bottle minus 1 mm (such as 59 mm) on the cardboard and cut them out.
- Draw a line on each circle, including a line passing through the center of the circle (Line 1), a vertical line (Line 2) measuring 40 mm at one end of Line 1, a point measuring 20 mm at the other end of Line 1, and then draw a dotted line (the length is recorded as L) between the point and the two ends of Line 2.
- According to the L value, a rectangular shape with a height of 110mm and a width of L×4 mm was drawn on the cardboard, and a vertical line was drawn every L mm. The big rectangular shape was cut open and divided into two identical rectangular shapes in the middle. The top layer of the rectangular cardboard was marked for folding, and hot melt glue was applied on one of the circle marking lines and the rectangular cardboard was pasted for reinforcement. The operations such as opening holes for the tie were carried out.
** 3. Simple Paper Cup Rocket Making **
1. ** Material preparation **
- A disposable paper cup.
- Paper shell.
2. ** Production Steps **
- He cut the disposable paper cup from the middle, cut it two-thirds of the way, and put the two parts with the bottom of the cup opposite each other into the shape of a wooden barrel.
- Prepare two quarter paper cups and put them together to form a long cylinder.
- He used half of the paper cup and the leftover cup from the first step to make a rocket propeller, and cut out the shape of a flame from the paper shell.
- Sticking the prepared materials on the cardboard, painting it white, drawing the background and adding details such as flags, patterns, etc.
