Urinate into the bottle up to the MAXIMUM FILL LINE. (The average man urinates up to 16 fl oz.) Add neutralizing powder into the bottle with urine. The extra air space in the bottle is to allow for fizzing action. Once the fizzing has stopped, you can pour out the neutralized urine OR slowly add the enclosed bottle of enhancer creating your desired deer attractant.
NOTE: Once the enhancer is added, the attractant has a 7-day life at peak performance.
