Query: Not worth it

I purchased this item for my child's birthday. After my brother-in-law who is in the military spent over an hour putting it together we took it outside to try the lava. Thank God we took it outside. The lava got all over everything including the kids. The pieces came apart. It was such a mess we couldn't even put it back together again. This is a huge waste of time as well as money!!
