Yeah Benoit, but on the other hand + air = + molecule = + thrust ... but you must be right ...

Not everyone is so lucky ... You have to believe that you have to trade to have Petit's "blessing" ... hihihihi!

Yes ... I give explanations, and you only pick up the last allusion ...
(Did you notice anyway, that I always did it maliciously, to tickle you?)
Petit wants to make scientific disclosure. The engineer in question, surely in luck, had the idea of ​​collating all the objects in the world, found on the Internet, early learning toys, with scientific and educational connotations, and intends to resell them…
He asked Petit for a boost (given the number of daily readings from his site), and he did so, because it goes in the direction of his "Knowledge without borders" objective.

Bonjour.

In this case, why not give a more aerodynamic shape to the blades? a bit like adenometers (spelling?), in black on the hollow side

Ahh it was premeditated then?
Hihihihi

I am the manager / webmaster of imaginascience. I was not particularly in the mood even if being unemployed gave me time to train and develop my activity. Finding the products, then the right suppliers, and then the explanations (because I don't want to sell "stupidly") was not a task.

I wanted to confirm that I did meet JP Petit, whom I knew very little (but for a long time with his excellent comics). I thank him again for having received me and making a page about me. I would like to help him with some of his projects (animated pyramids).
It took a little time to give me a boost because he is very busy with his activities (site, association). He sincerely liked my demos and gave me some ideas. He did not know much of my curiosity and I did not disappoint him it seems to me.

Here ! Do not hesitate to give me comments on my site (sorry for some spelling mistakes, I must one day think of correcting them all). I will take it into account to improve what I can.
