A 100mW laser is capable of causing permanent eye damage in 0.000001 seconds. Half that for a 200mW.
[highlight]Any laser over 5mW is illegal to import into the USA, since the maximum permissible exposure for 5mW is 0.25 seconds, which is reasonably assumed to be longer than the blink reflex.[/highlight]
You should learn what you're dealing with before you go shining it around your school, since if you are arrested and made an example of it would put our hobby in jeopardy.
Anyways, enough with the heavy lecturing, just be safe, kid. It really irks me to hear someone wants to buy a high powered laser "to shine at things at my school"... This is how Australia got its laws changed to make ALL laser pointers as illegal as guns.
Unless it is approved by the FDA by having all 5 safe features (Power key, safety interlock key, shutter, 2-second delay, and power light.).
