pour 1 to 2 inch of baking soda in your tub put lid back on butter tub sit 2 oz shot glass on top next to the edge then put the knot end of the yarn down in the glass let it hange about 1 inch past the glass bottem and cut
pour vinegar in shot glass the wick [yarn] will probley float to the top but it will sink in a little while it will start to drip in to the baking soda you could tie a small glass or plastic bead on the end of the yarn to sink it
thanks guys i hope this is what yaw guys wanted after vinegar has driped in tub pour off old vinegar slow then repeate when baking soda gets low just add more baking soda i do this 1 to 3 times a week its seams to keep the smell down too or it does in my room peace
sweet420 it will work for a room up 11ft by 11 ft no you have to have a WICK cotton string works the best but i had yarn so thats what i used you can use a strip of paper towel, shoe string, a strip of cloth NO you cant use 1/4 tubing it would drip too fast MY room size 4ft by 7ft a room bigger than 11ft just get a bigger butter tub and bigger shot glass 4oz - 6oz
Wait, what? Did it sting your eyes, or cause an allergy or...?
I see a lot of yeast-based generators on Amazon, people use them to pump CO2 into fish tanks in order to grow plants in the water aka aquaculture. And plenty of comments saying don't even bother, put some baker's yeast in a beverage bottle with some sugar and water.
It does seem like the vinegar->wick->baking soda thing is a lot cleaner, or at least less gross.
