Blacklight and Ponies
My daughter has been trying out all of her toys on the black light table to see which ones glow the best. Even if they don't glow she has a lot of fun pretending that the lit up area is water or lava or pretending like all of her toys are throwing a big party.
Here is a picture of her My Little Ponies having a party on the black light table.
As you can see a couple of them glow really well but the majority do not.
Anything that your child finds fun in regular lighting becomes twice as much fun
when you shut off the lights and add a fun black light glow.
