Fluorescent bulbs tend to work better than incandescent. The (incandescent) bulbs you get around Halloween that look like black light bulbs that screw into a lamp base aren’t usually strong enough. You can find a fluorescent UV light from any pet store (look for ‘Urine Off’ types of packages, as urine glows under a UV black light) – that’s the cheapest and most accessible UV light source we’ve found. You can easily test out your black light by taking it near the box of laundry soap and see if the soap glows bluish-white (turn off the lights first!) or bringing it near a bottle of tonic water (glows blue). If your light causes these things to fluoresce, then it’ll work. A black light and UV light/lamp have the same name for a variety of different bulbs that emit in the UV.

(From Unit 8 list.) Thanks! Will a black light work instead of a long-wave UV lamp? (From Unit 8 list.) Thanks!

I can get the shopping list but can't get to the directions or videos. Can you help me. Thank you.
