Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Get the Peices

you need:
1 white (or shiny gray) rod
1 blue or shiny blue rod
2 light gray 1 hole connectors
1 rubberband (i like using the blue ones in certain knex sets. They are stretchy but powerful.)
1 connector rod
2 hands
1 target (a target is not a person or animal. a wall works best.)
time (approx 5 minutes if you are slow)

Step 2: Handle and Bullet

build one of each

Step 3: Bullet and Power Meet

this is the part where the bullet and rubberband meet!

Step 4: Assembly

put the handle and bullet together.

Step 5: Firing!

take the constructed gun and hold the handle in your whole hand with the bullet pointing away from you. pull off the safety. then with your other hand pinch the loop of the band with again your thumb and index finger. pull back and let go of the band. the bullet should fly like a dart.

Step 6: Enjoy!

i fired it and i made mine go 21 feet and 4 inches measure yours and post it!

Step 7: Additions

instead of putting a blue knex brand rubberband you can put one of the 7 inch ones HERE[]

a guy on youtube suggested this and his went 40 feet!

    i have a WAY better way to use this gun.. leave the safety on, and flip the bullet around so the front of it is facing you, and the safety is facing away. then just pull the elastic. the safety goes MILES cheers for the instructable much more clear than half of the complicated knex guns on here

    Many very tiny and weak guns. This gun ain't exactly a gun that would be useful... i built the gun but it only goes like three feet, and I have good rubber bands...


    well then your rubber bands aren't as good as you think because mine went 21 feet and 4 inches with the blue knex brand rubber band! look at the last step for a pic
