I am 22 years old and do not even fill out a size A. I am looking into suction devices, but would like to try to make my own because of the price. Also, I live at home so I would have to be able to buy everything at local stores such as walmart because I cannot have anything shipped. Thanks!
I've been making them for years.... modifying every day items... a good start is 3" or 4" PVC pipe end caps.... I used to thread in 3/8 to 3/16 barbed hose nipples and add vacume hose... get a hand brake bleeder pump from the auto parts store... Walmart sells a battery operated hand food saver vacume pump..... and you can also use large plastic tumblers and mugs if they fit. if you have a heat gun you can resold things to fit better... these days none of my home made domes have hose fittings... I just slip the hose between my skin and the dome... pump out the air and slip the hose out. they will stay attached for hours...... have fun experimenting.
