World's Smallest Cellphone Jammer Looks Like a cigarette Pack
Disguised as a pack of cigarettes, the so-called "world's smallest cellphone jammer" disables a cluster of frequencies, mainly GSM and 3G signals within a 32-feet radiius — turning crystal clear babbling into ear-splitting static. This could come in handy when trying to block out mommy from shouting at daddy for the umpteenth time. Price for quiet? $46.
In the U.S. cellphone jammers are illegal, with anyone caught with one punishable with a fine of $11,000 and up to a year in jail time. I don't know what the laws are in your neck of the woods, so consider yourself warned before hitting that "Add to Cart" button.
