ok well i dont have ny of that plastic but woul i be abe tpo cut up 2l pop bottles and use those in a vacuum former? i know you can use a heat gun with pop bottles to get the odst visor so would i be able to do it in a vacuum former? and if soo how would i go about heating it up without the oven or buying one. would i be able to use a hair dryer? like over a long period of time would it work. or rest a jar of boiing water on top of it so it just gets heat?
