today i will teach you to make a 20cm x 20cm crossbow using bamboo skewers, tape, elastic bands, and a straw or empty pen tube.

Step 1: Get Your Ingredients

you will need 4 bamboo skewers, a lot of elastic bands, tape -electrical works best, and empty pen tube or straw.

Step 2: Secure It Up

use elastic bands to secure 2 bamboo skewers together - i cut the tips off the skewers because this is not the ammo or 'bolt'. after this step you will have two sticks of two bamboo skewers secured together.

Step 3: Secure It Again

secure it with tape and elastic bands like in the picture

Step 4: More Securing!

secure the tube or straw on top

Step 5: Secure an Elastic Band!

secure the elastic band, to the sides and you are ready, i use more bamboo skewers as ammo! also you can use a bulldog clip as a trigger
not to be rude or anything, but you call this easy????
yes. But it's not a crossbow. It's a slinshot with a similar shape to a crossbow. In a crossbow, you get power from the flex of the wood, not an elastic band.
sorry to burst your bubble but this is not a crossbow, it is a slingshot that has the same basic shape of a crossbow.
The picture is unclear
