The stuff released stinks. You get enough material to annoy quite a few people. You can't make it go way once you release it.

When I tried these at school, the stink stayed for all of 5 minutes. The packaging was different than what is on the preview here. Perhaps penguin changed suppliers. It gets 2 stars just because the stink was VILE while it lasted. These are good for bumping your order up a few bucks to get stuff from a special. I'm dissapointed.

this prank is awesome!!!!!! my porch still smells a day later!! BUY IT!

Dam this stuff works! I set 1 off in class and i had to stay out for 3 hours!

Woah!! I set one off in my math class and we had to evacuate for about half an hour because it stinked so bad..

Penguin Rocks!!!!

My friend busted one on the first floor of our school steps. Not only did it smell on the second floor and in the gym, but it also filled the halls of the third floor. Teachers were coming out of classes!!!!!!!!!!

You should get this! It really works. I put one in one of my friend's desk at the office, and man does it stink! It took awhile for it to clear out! Ha Ha Ha!

After setting one off in my school hall it had to be evacuated saving us over an hour of bordom. Now I buy them with every order.

These stink bombs are amazing. They look so cool and scientific, they are about a little more than and inch high. They smell really bad for a long period of time. SUPERB!

This is the best!!!
