How to make a sploof

From ETCwiki

A sploof is a device that allows a smoker to smoke normally, and exhale his or her breath into the sploof, through its filters, and out the end. Sploofs are used to eliminate the smell of tobacco (or other) smoke, even when used indoors.

I have heard many people talk about sploofs and have tested many methods of sploofing. After about 20 home made sploofs, I came up with this idea, which works better than ANY toilet paper roll sploof. This is an ODOR ABSORBING sploof, it has active ingredients to absorb smell. It will outperform any regular sploof, and will also last much longer.

Sploof Materials

Empty water bottle (plastic)
Baby wipes (or paper towels if you are desperate)
Baking soda
Cat litter

How to make a sploof

Grab your water bottle, and some scissors.
On the bottom of the water bottle, make 8 snips around the bottom of the water bottle. Each cut should be less than 1cm long.
Blow through the sploof, make sure you can still pressurize the bottle (it should puff out just a tad if you blow hard into it)
Insert about 10 baby wipes into the bottle, and compress them to the bottom.
Pour cat litter (less than 1cm deep) into the bottle, on top of the first layer of baby wipes.
Insert 10 more baby wipes, and compress on top of the cat litter
Pour baking soda (only a few millimeters deep) into the water bottle, and shake a little so it settles on top of the baby wipes
Insert 10 more baby wipes on top of the baking soda layer. Your sploof should have the layers in the diagram below
Get 2 baby wipes, and wrap them around the bottom of the sploof, then tape them to it. This is a catch for any cat litter or baking soda.
