Watch and you can see the guy behind him with a knife quickly jab up at it when he lifts it. The horrible thing is if that is actually cement the incredibly dangerous effects when you breath the dust into your lungs.

I'd like to see findthumb actually work too. Has it ever? Or did they just make it up, because if so, I can think of some other invocations to award:

*shazzam: electrifies sift! Zzzzzt!
*bose: improves the audio of a sift
*snowcrash: infects users who watch your sift with an ePlague

So go crazy!

cement is caustic/toxic like Jordass said.
You do not want that stuff in your eyes/nose for sure.


Yeah... I'm sure the average joes did not think about the possible medical effects of dumping a bag of cement on their youngest employee's head.

Cement or pure plaster would be pretty bad for the eyes.

Firstly, cement when wet is highly alkaline (~pH 13) which would with sweaty skin could cause 1st, 2nd and even 3rd degree burns depending on exposure.
Forget about the eyes, and mucous membranes.
Exposure to airborne dust may cause immediate or delayed irritation of the eyes. Depending on the level of exposure, effects may range from redness to chemical burns and blindness.

Also, the chemical reaction when plaster mixes with water is exothermic. Which could also lead to burning.

Right, I think i'll scrub plasterer off the potential jobs list.
