a Scent Bomb is a product made by Tinks. its basically an orange plastic bottle (small, like a small vitamin bottle) with a lid and an unscented wick inside. you put scent on the wick, whether it be vanilla extract or urine, pull up the wick and use it to attract deer. then, at the end of the day, push the wick back inside and close it up to bring it home wit u. you can normally get them at any sporting goods store or walmart. they're pretty popular.
Here we just use an empty 35 mm film canister and some cotton, it does the same thing as what you are saying...
