@Felthry wait what? was flash paper also semirigid and very bouncy?

@lioness no, but they're made of the same thing in the same way that HDPE (milk jugs) and LDPE (ziploc bags) are made of the same thing--same thing, different structure

@lioness the nitrocellulose molecules are arranged differently in flash paper compared to ping-pong balls or gun cotton, but they're still all nitrocellulose

@Felthry should I try lighting a ping pong ball on fire & see what happens?

@lioness it will burn quickly and without leaving any smoke. be very careful if you do this, or just look it up on youtube
