I messed around witht he double or nothing and if you land on the back stirng and curl in oyur non throw hand index so the back string drops and twist your fingers a little you get a eiffel tower

I think 3 months or something, I'm not sure.

It works better with the middle string.
Sigh... all of you are trick stealers.
I discovered Mickey did it in his worlds 2008 performance. You might not know it, but the knot trick he did before doing his slanted tricks is actually an eiffel tower with a "And Whut" pop in it. Then, he threw the strings into the thing and pulled so that it created an awesome effect.
