i had those
"JUST ADD WATER" snow thing. u add small amount of water and POOF snow pops out!
Well, I
'sprinkled' some of these snow onto the 'TARMAC' of my small display case along with my Hasegawa Aloha B732. Next thing i know,
fungus!!! it made my aloha fuselage to go dark... i was about to cry!!!

oh well, i might need to get IF200 Aloha B732 now...
it may well be that Hasegawa B732 was not dry? i don't know. i bought it from a guy in Canada, so i have no clue when it was built. but, i think that it was built awhile back though, so it couldn't have been the moisture on newly built model... odd...
or it may be that these 'ADD WATER' snow are
chemical stuff that's bad for plastic? who knows, i know i probably won't be using these fake snow on my models anytime soon.
btw, this 'display case' was the one u get for 2 bucks at outlet store for DIECAST CAR DISPLAY 1/18 i think?
btw, this "just add snow" i bought during christmas times at a local mall. it was so popular here during last holiday, lol.! so cool! add water, POOF, snow rises!!!
nonetheless, i love your snowed airport!!! i hope this is the different type of snow you are using!!!
