Let's get going!
First, get your stuff.
Take a look at the table below and make sure you have the right material.
|Pencil||1||-||4 skewers stacked together using rubber bands|
|Cardboard tube||2||Length = 10cm||-|
|Single hole puncher||1||-||-|
|Cotton ball||3||1” dia (approx.)||Table tennis ball/crumpled paper ball|
Step 1: Take one of the cardboard tubes and draw the line at the centre like this. Then cut through the drawn line.
Step 2: Now roll the cardboard tube that you had cut through and tape at the end to secure it, like this.
Let's call this as cardboard tube A.
Step 3: Take a pencil/marker and mark a point at any of the two sides of cardboard tube A and punch a hole on the marked position.
Step 4: Insert a pencil through the tube and mark a point on the other side. Then punch it.
The final form looks like this!
Step 5: Now take the other cardboard tube and make a U shape at any side.
Make another one right in front of the previous one.
Step 6: Now cut only on the straight lines of the U-shape.
Step 7: Repeat the same process for the U-marking as well and attach a rubber band on either mark like this.
Secure it with a tape!
Step 8: Now put cardboard tube A into the bigger cardboard tube, like this.
Step 9: Finally, stretch the two rubber bands on to the pencil and load the launcher with an asteroid at the front.
Launch the asteroid!
A rough asteroid is racing towards the Earth. Use your launcher to destroy the rogue asteroid and protect the people on Earth!
