Making my first Crossbow

Yesterday, I decided to make a Crossbow. I got the idea from a T.V programme called the Mythbusters on Discovery Channel. The programme is about people who heard of stories and try to make them true. For example Archimedes built a big shield with lots of glass pieces to reflect sun rays to burn down the Roman ships. So, the Mythbusters would try to build what Archimedes built to destroy a ship. This time, the Mythbusters tried to make a Crossbow out of paper and homemade glue and this project worked! I was fascinated by this creation; that they could make actually such a strong crossbow out of flimsy paper! That was why I decided to try and make a Crossbow. These are the steps:

How to make a Crossbow

Things you need:

1. two rubberbands
2. string
3. double sided tape
4. a pair of scissors
5. musking tape
6.wooden chopsticks
7. ice cream sticks.
8. paint(any colour you like)

Steps

  1. First, tie two wooden chopsticks together.

  2. Then, using a double sided tape and string, attach a ice cream stick to the middle of the pair of wooden chopsticks.

  3. Next, use the musking tape to join four ice cream sticks to the first ice cream stick. It should look like a long house.

  4. Then, tie one rubberband to each end side of the crossbow. (you might want to use the musking tape to secure the rubberbands)

  5. Lastly tie a string to each end of the rubberband with a short piece of string. The string should be about 20 to 30cm.
Optional: You can use the rest of the ice-cream sticks to extend the length of where the arrow would be before fired.

Caution!
do not shoot the arrow at someone. Or Else!

Your Crossbow should look like this

How do you like your crossbow? Did Jabez make one for himself?
