Sometimes you just want to drown out the noise around you — starting with cellphones. While cellphones are great communication devices, people who go overboard, spilling their life stories out loud in public tend to become annoying. Silence them with the world's smallest cellphone jammer.
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.
