Eiffel Tower

Your double hyperboloid of revolution to which you carefully
transmitted a strong kinetic moment hangs down in the middle of
the string when you take with your right hand fingers the string which is very close to this same hand. You obtain a formed
triangle of the right stick, the string and your fingers where you can point your left stick. Then you take the left string with the hand of same side and you points in the triangle which you have just formed your right
stick this time. The whole is carried out without releasing the sticks of the hands. You must obtain something like that (see photo
on the right) then you make goes up the diabolo from the bottom to the
top while launching it. You have to manage to make it arrive at the top. If you drops all the strings (while keeping the sticks) you finished
the trick.

The Best End: you put the left stick at horizontal while pricking in the triangle top of
the right stick then you make slide the knot so that the right stick is not there inside (the knot) any more . You
can then release the right stick and VERY SIGNIFICANT to scrape
you the head (or another thing) with the right hand. Then you launches
the whole while letting slide the strings on the sticks. (see second video)
