In this instructable i will show you how to make a dangerous crossbow out of:
3 pencils(unsharpened)
One Rubberband(general size, thick)
Masking Tape
Hot Glue
Ink Part of a Pen

Step 1: Glue

Take hot glue, and glue the two pencils together. glue on one side, and leave no gap between pencils!

Step 2: Glue...again

Take the third pencil, and lay it near the unsharpened part of the pencils, centered, on the glue side!

Step 3: Rubberband

Take some scissors, and cut a little groove in the eraser. Then, take a rubberband and put it in the groove. Hot glue in place.

Step 4: Other Side...

take the part of the rubberband that isnt glued, and s t r e t c h it out to the other side. glue in place

Step 5: Take the Duct Tape

just a small bit of it, and put it in the middle of the rubberband, on the side where there isnt any glue. the tape should be able to fold over the rubberband top and bottom.

Step 6: Insert the Inside of the Pen...
