Fairly cool product. Here’s the deal: the item is small packets made of plastic about the size of an instant hot chocolate pack, but more rectangular. You toss a packet in your fire, and as the fire starts to burn through the plastic, the material inside ignites and you start to see blue and green flames in your fire. The effect is neat. We used it for a fire in our fire pit during camping. To really get a cool effect you’ll have to use more than one pack at a time because the effect is pretty localized on the area you threw the pack in and the packs are relatively small as mentioned before. We cut open a pack, and the material inside looks like blueish sand. We wanted to see if we could get the effect by pouring this sand directly on the fire or spreading in all over the wood, but no luck!! Not sure what is so special about the bags. They seem to be just tough plastic. But the sand only seems to burn well if it is inside the bag, as per the directions from the manufacturer. Regardless, the effect was fun. We enjoyed using it and added a little ambiance to the ghost story telling! Also, because the effect was created by chemicals, we DID NOT cook any food over the open flames. You should probably cook any hot dogs or marshmallows first before you decide to use this product. I’d buy this again because it wasn’t too expensive and it added a little fun to our fire.
