Review on Make Real Terrarium Necklace Glowing by Robert Blanton

I thought it would be a cute fun gift for my friend's daughter but we were all disappointed when it didn't glow in the dark. The kit says the 4 colored sands should glow in the dark, but they don't. I even tried putting them in the light for a full 24 hours. It didn't work so my friend said they might need real sunlight so I waited for a really good day and left them in the sun all day. Didn't walk in the dark yet. Also the key fobs don't light up so I don't know what happened if I had a broken box or other people had this problem but my friend's daughter was very upset that it didn't work. I ordered her a set from another company for Christmas, so I hope it fits, otherwise I'll be very annoyed.
