Recycled Pizza Box Boomerang

this is a fun instructable to do with kids after having takeout pizza.

all you need to gather from around the house are....

a empty pizza box
scissors
marker
12 inch ruler
& a throwing arm

use the scissors to cut the lid off the pizza box.

place the top to the box on a table.
place the ruler in the center of the box.
trace the 12 inch ruler with your maker.

while ruler is still in place
use your marker to make dots at 5.5 in. and 6.5 in. on both sides of the rectangle.
this has now made the point were you will cross the ruler over the center of the first rectangle.

place the ruler between the dots that you made in the last set
this should create a X shape.
if it does, now trace the ruler.

with your scissors cut out the outline of the X

the only way the boomerang will return to you is if you shape the blades up words.
place one of the blades in between your two fingers
run your fingers upword starting at the center of the X toward the end.
repeat this on all four blades evenly.

place the boomerang vertical by your ear.
then throw in an upward
the boomerang should return to you.
if it doesn't just add a little bit more of a curve.
