A glow in the dark session is a fun and different experience for seniors and results in some really unique portraits. Here are some tips and links to supplies to create your very own session.
Blacklight
Paint and brushes
Powder
3 oz. cups and Press'n seal plastic wrap
Drop cloth
Fake eyelashes and clean mascara brush

Preparation
Almost any type of background can be used, but some fabrics will react to UV light (blacklight). Gather all of the items from above, as well as any other items that might glow. I plugged my blacklight into a Vagabond mini and wandered around my studio to find items like the sunglasses and earbuds below.

Blacklight
One blacklight is enough. We used a second one in the makeup area. i used a 24 inch blacklight from Amazon.com. The light can be handheld or clamped to a lightstand.
Paint and Powder
You could use one or the other, but both are useful. For colored eyelashes, paint fake eyelashes before applying. The paint come easily out hair. Use paint first, then apply powder laying down. To apply the powder easier, put them in a small cup (like a 3 oz. bathroom cup) with small holes punched in the bottom. You can seal it with Press'n Seal wrap.
Other Items
You can purchase specialty makeup for this purpose, but I found paint works just fine. Many nail polishes are UV reactive,
