smokey-nitro

ohh crap imaginitive maybe but i better get these spelling right lol

"shattering chewing gum from pavements" this was my idea exacly its a pproblem alot of big cities have and they only thing to combat it is to power wash it but liquid nitrogen would do it ten times better maybe farfetch but mu 14 year old mind is quite imaginative i reckon it could make ya a bit of money too

i can buy some liquid nitrogen over here for less then 90c a liter and the dewar for holdin it costs a bit though but my main question was not the price or the implecations but could you spray it out of a back pack type thing

haha shut up

ok i was not gonna let my idea out but i was thinkin of makin a back pack or rather designing one that sprayed LN2 at chewing gum on the ground and then shatter it and scrape up off streets its ingenous jus designing it is hard i was think of a presure think that let out presure when it got to much and the presure in side would pump it through so no pumpin and lower presure ta-da

would it be possible to spray liquid nitrogen out of a weed killer kind of back *pack

would it be possible to spray liquid nitrogen out of a weed killer kind of back back ?? ad is liquid nitrogen hard to get and is it expensive???
