I know it's easy but it is Tricky! :)

How did he do that?
I know he started from a Houdini mound right?

Please help!

(Please help me!, it’s Ok in words, but much better in Video demonstrating it how…)

Cheers!

You just do the first step of Kamikaze, then pop it off to the back. Then, you flop.

Either do a houdini whip, or the first part of kamikaze.

Houdini whip is the first step of this trick:

After you get into that mach 5 mount, you pop the yoyo to the back. Then pull and you got floppage.
