If it's made from plastic, pour some HCL on it a few hours before they usually come, probably pH 3 will work ok, if you are serious go for pH 1 but keep in mind it is 20 times stronger. It should burn their hands a little but they will recover and wont know what it was (just wash it off with some baking soda and water when they leave) If the skylight is glass, don't do it, it will eat through the glass.
In that case use some sodium peroxide (Na2O2), just put a few pellets on the skylight or near it, you can try adding water but then it will not be as powerful. When they touch it, they will have what looks like little scratches on their hands and it will bother them for a while and it burns. Just wash it off with vinegar and water later. You will be able to get some in a local store in Waterloo or I could mail you some, it is not dangerous when properly sealed.
O yeah, don't forget to wear gloves and long sleeves.

I'm afraid to ask, but how do you know so much about this? Hehe, its made of glass. Where can I buy sodium peroxide (or what household material is made from that stuff)? This doesn't sound like a bad idea, especially if its in pellet form, kids will grab it right away and try to figure out what the hell it is. Will it actually iritate their skin right away or does it take time? I'd rather they play with it and rub it all over themselves first and then the pain kicks in.
Let me know, good idea.
