New inexpensive incendiary device

Strawberry Pop Tarts may be an inexpensive source of incendiary devices. Toasters which fail to eject Pop Tarts cause the Pop Tarts to emit flames 10-18 inches in height. Last year, an article by well-known newspaper columnist Dave Barry noted that Kellogg's Strawberry Pop Tarts could be made to emit flames "like a blow torch" if left in a toaster too long. . . The present work describes our independent verification and experience with SPT-based combustion. . .

Its the sugars, which make it burn so well.

i would bread would work better, since it's full of holes that would make for better ventilation than a dense poptart. maybe the poptart is made of a more flammable material.

Where are the controls? Fires started by burning things in malfunctioning toasters are nothing new...ask the local fire department. Is there any reason to think a pop tart is anything special compared to anything else that burns in a toaster?

You forgot the warning:
Don't try this at home!!!!!!

This is a physics website, I would hope that people know this

If not, natural selection, here they come...

Nitrocellulose also has this effect on toasters.

I was not aware that Nitrocelluose was a popular breakfast snack.
