This is how to make a cool mechanical slingshot that fits on your arm and can be used in many ways,
it is simple and many of these items are in your house ( trust me, look at the picture. thats just my drawer.
you might need help with an adult, but it is simple.
Step 1: Step 1: Stuff to Get
This is my first thingy, so dont hate.
First, you are going to need an old clock.
if you dont have one, "accidentaly" break one.
For coolne- AH i hit my knee. ow ow ow ow.
for cooolness, you are going to take the diode out.
you also need to, if it has a wire to an outlet, cut the wire into 2 medium lengh pieces.
Step 2: Step 2: Attaching
You are going to want to, if there are any wires on the diode, pull them back or cut them.
Then, put the 2 wires over the diode and either tape with clear duct tape, hot glue it, or fuse/wire it.
The you will strap it on your arm.
Step 3: Step 3: Add the Slingshot
you will need a retractable thing that you can push down so that it is flat on your arm.
anything that fits my description will work.
then, add the rubber band, and surround it with wires.
Step 4: Step 4: How to Use
One more thing if you want it to be cooooooler. add an on/off switch attached to a motor or and kind of thing that makes noise.
when you turn it on, if will make a cool wrrrrrrr ing noise.
How to use it, dont shoot close or in the eye.
it is dangerous, so dont wear it to school, unless your feeling snazzy.( but pull it down)
If you make this for a science project, give me the credit. do0nt be a wet blanket.....
