I've just been sent a little movie cliplet, where 5 geeks and a geekette=20 place 4 mobile phones set at 90 degree angles so North/south, East/West on= =20 the table with aerials pointing towards a cluster of unpopped corn in the=20 gap in the middle. The fifth person then phones the phones and the corn=20 starts popping before your eyes. Two things strikes me as odd. 1. The fifth person must be very quick on the dialing button, unless the=20 phone can do multiple dialling within ms or less of each number. Is there a= =20 loopback phone number for mobiles in the US like land line phones have, to= =20 test the lines? 2. It is possible that they throw popped corn into the circle as the camera= =20 work is a in focus, but hand held and shaky, so with clever cutting it=20 could be like the 3 card trick. We see what we are meant to think we are=20 seeing. I suppose I'm wondering if 4 GSM phones (I'm assuming they are GSM) which=20 output what 2 or 3 W max really be capable of this? I don't know 4 people to try the experiment with and I only like toffee=20 popcorn.
