This is great for including in birthday cards as it is not only a gift but a puzzle as well!

Step 1: Use the Newest Bill You Can Find.

Using a $5 or $10 bill is best, because the design on the reverse helps to hide where the crease is, and makes it much harder to figure out how to open it. This will work with any bill, but a newer one will make nice sharp creases.
<p>Great steps, easy to follow. </p><p>Tried it with Canadian polymer bill. Good news: It doesn't rip. Bad news: our bills are not as skinny as US ones so you can't tuck the sides at the last step. </p><p>(And polymer bills hold their folds after you're done. They will NEVER lay flat again.)</p>
<p>After the last step if you want to make it even smaller then just fold it in half and tuck one half into the other. I only just managed to do that but it put terrible strain on the bill &amp; it tore it a little, so I would suggest not doing that if you ever wanted to use the money again.</p>
It's cool!
on step 7 u can put in up to 2 dimes if u r careful........<br>makes great money hide.
This is great. I can't believe how tiny it is! I will enjoy doing this to my friends' money.
i have to say good instructable,but u oweme 1 dollar. u didnt say that people might rip it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In the US, any bill is valid if you have more than 51% of it. go to any bank and they will exchange it
WOW that's small. i couldn't get the second edge in though because i was afraid of ripping the bill. i think i'll try it again. great instructable!
i folded the tip over then tucked it in. and i also agree about wat u said
This just ruined my day! I am new to this site and I was thinking about unique things I can do and post. Well, this was my idea and its already here. :'( I would use this to bet people with. "I'll bet you a dollar that you can't open this without ripping it in a minute" Ah, I made lots of money that way.
harder to do with Australian (plastic) money, but harder to rip too!
I got it, but used a 1 dollar bill
now i really dont get step 12!!! How do i do it
If you try to match up your bill with the picture (using a $10 bill) it should be easier to figure out. You actually fold in both ends, folding the three triangles under.
wait am i right on step 11, just flip it and fold it?
how do you do step 11, its really hard and i dont get it. Please Help
Do it with a $1 bill with the bill flipped over (Washington's face would be on the back in step 5). When you're done, his eyes are peeking through the two strips on he back. It's pretty sweet/creepy.
could you add another photo with the bill next to something, like a quarter to show the size?
Ah, but that's half the fun in making it!
I agree, it would be a good idea to take a picture of it next to something to compare sizes. Otherwise, cool Instructable!
You guys should definitely try this out! I just did this and it is real small!
Damn thats tiny. I just did it. Great Instructable!!
