Picture of Rattlesnake Egg Prank
What I love about this prank is, well... everything. It is very simplistic, cost little to nothing, provides a great scare, and you can not get in trouble for doing it! It consists of telling someone you found a rattlesnake egg and it in the folder, then they of course open it and a very loud rattling noise starts, scaring them very good. And yes I know, rattlesnakes give birth to live young, but most people don't know that or don't think about that because they just want to see it! I have gotten my teachers, friends, and parents with it and it always ends in a good laugh... of course after the screaming and what not.

Step 1: Materials

Picture of Materials
Here are the materials needed to do this prank:

Clothes Hanger (Metal)
A large washer or some other type of ring with a hole in the center (Mine is a Hard Drive Disk Spacer)
Rubber bands (Probably a lot because you will break a few until you gt used to how much to tighten it)
A manila envelope
A magic maker (not needed, but is a good add-on)
Wire Cutter
Pliers
Tape Measure

Step 2: Close Hanger

Take your clothes hanger and your envelope and just cut the top off of the clothes hanger and discard the top. Then, Straighten the hanger.  Now bend the hanger at a 90 degree angle, 6 inches down. Now find the width of your envelope. Mine is 6". Subtract a half and inch from that and you have the length that the middle of your clothes hanger should be. After you do this bend at 5.5" (for me), a 90 degree angle. Now you will have a lot of clothes hanger left. Just cut that to 6" from the last bend. Now you should have a "U" shaped clothes hanger.

I remember my dad showing me one of these when I was really little. Thanks for bringing back one of my earliest memories.

A cool idea would be to take one of those sound recorders from a birthday card, recorded the sound of a rattlesnake, and rigged it up so it would play when you opened the fold in the folder.


Bad idea - the snake would bite you for sure.

I made one of these when I was in grade school. I used a regular envelope.
then I gave it to my teacher saying it was from my mom! He made me re-wind it and took me over to another teacher to show her "What my mom had written" 
This is indeed a primo prank and I can hardly praise your mad skills heartily enough.

But on a smaller budget with less time,  we got some nice screams from the same sort of contraption done with a bent up paperclip, a fairly good sized button, a cut-and-retied rubberband, and a plain ol' legal envelope.

(Yours is MUCH more elegant tho' so keep up the good work.)

What happened to your measuring tape? it's really beaten up.

Also, how exactly does it make the rattling? How is it triggered when the envelope is opened?

as soon as the pressure from the rubber bands overcomes the pressure from the envelope pusshing against the washer, it starts spinning the washer and the washer hits against the envelope

We had one of these when I was a kid, and I remember just about everyone that opened it was surprised.  Great write-up!

REMEMBER:
Rattlesnakes are PIT VIPERS.
Vipers are VIVIPEROUS.
(They don't lay eggs, they bear live young.)

This would be a great prank for the teacher to pull during a biology class on snakes. Everyone would remember it.

This was a cub scout project when I was a kid. I pulled it off on my 4th grade teacher. Our den mother was the coolest!!

When I was a kid I fell for this trick, then made one for myself to use on other people. Oh the memories!
