wonder if the 'coffe cups' make a better plastic with acetone than the 'packing peanuts' do?
You just need a non-polar solvent that could be potentially less dangerous, but they may not be as readily available as acetone.
PS. the pipe was standard 20mm plumbing PVC pipe
please respond.
however, if layed intop of a mould, and in contact still with some solvent (gasoline or acetone), it should eventually seep intot he mould so long as the air can escape the mould as the polystyrene come in.
any one know how to prevent this?
you make napalm by adding aluminum soaps to petrol (gasoline)!
this would be flammable due to the acetone and the drying plastic would be like napalm (sticks 'n' burns) but not when dry. where did you get that idea from?
Napalm=Gas+Al Soap
weird plastic=Acetone+Styrofoam
i know that you could also use gas as the solvent but 2 things- gas is more flammable and it rather volatile as compared to acetone.
here acetone is used instead of gas
(PS- Textbook explainiation for 'volatile' means it evaporates easily, not explosive but often is.)
napalm, when lit almost explodes then starts to burn. do you really think i want to go to hell directly?
this 'might' be an explosive but it won't be napalm. it will be somthing else.
