Do the spores really accelerate at 320,000 m/s^2
This is much faster than the speed of sound. Also, is s^2--square seconds? If so, this doesn't sound like a speed sort of unit. I would have expected meters per second.
I teach high school science. My AP Environmental Science class just visited a spaghnum bog and your article fits really nicely with our discussion. I'd also like to use this information in a nature column I write, but wanted to check on that speed--isn't that orders of magnitude faster than the speed of sound--is this possible? I have no idea.

Thanks!
