hi there can you pop your popcorn whit cellphones like they do on you tube http://www.youtube.com/watch?v=K1rRvExSuCc

No. It's a bluetooth commercial.

In fact, Grant has stated that they will NOT do this on the show because it is so obviously fake.

If you go and try to find the "behind the scenes" thing of this trick they will show you that they have a microwave under the table. The microwaves still allows some of its radiation to escape which in turn pops the popcorn.
