Query: Landfill Material

My five-year-old has been begging for this toy for a couple of months and we finally let him have it for his birthday tonight. He had a horrible time trying to find a car that would work with it ... and he has no lack of Hot Wheels cars. The launcher does not have enough force to get any of his cars to the top and he has to help them along by hand. But ... then they get stuck in the too tight spaces and too sharp curves. He's sitting with it now, trying to figure out how to make it function properly, but its not holding his attention enough not to check out the cartoons on tv. The only thing that seems to work is the slime coming out, although not at the proper time ... and that's the only part he seems to be enjoying. I'm sure that when the slime dries out this toy will not be used again. A complete waste of money. If your child is into volcanoes, as mine is, I'd recommend trying to find a volcano kit in the kids science aisle instead. Skip this bit of junk.
