Caption: I feel vaguely wrong about showing this photo. It's like explaining how a conjuror's trick works. Or looking up someone's skirt. But, yes, the secret of the cupcakes is hereby revealed.
Contrary to what some national papers may misreport, the cupcakes are indeed electric and not petroleum powered. Allegedly they charge the batteries with solar cells.
There were something like 14 of the cakes roaming the playa this year, spreading good cheer wherever they went. They're reproducing fast - there were only 5 in 2004.
