Review: Rainy Afternoon Engineering - The sky opened up hard while I was hosting the young ones at the beach house, so we hunkered down and cracked open this mousetrap car kit instead of scrolling on tablets, which are basically banned when I'm in charge. Guess what-- they love it. But also guess what, that means I get to be engaged with them rather than doing the same thing myself. As adults we have to take the lead in this. So anyways, it was exactly the kind of hands-on distraction I wanted—two complete builds in one box meant the nephew and niece could each have their own rig to tweak and race. We grabbed a pair of pliers to yank the staples off the traps, adjusted the leverage points on the sticks, and spent the next hour arguing over traction versus speed. Watching them watch the cars convert stored energy into motion across the hardwood floor was satisfying enough, but hearing them ask why one car spun out while the other zoomed made the whole thing worth it. My girl walked in midway through testing, saw the hallway turned into a drag strip, and just shook her head laughing. It kept them engaged without feeling like a forced lesson, which is the hardest thing to pull off with kids under ten. Instructions ran a bit dense in places, bundling multiple steps into single lines so you have to decode a few diagrams before snapping pieces together, but adult supervision fixes that gap fast. The mousetraps themselves are functional but require care—spring tension is real and safety matters around little fingers. That said, the components held up to repeated crashes into the baseboard without snapping, and having two kits means less fighting over parts during race day. Five stars because it solved a weather emergency with something genuinely educational. Sometimes the best lessons happen when you're too busy competing to realize you're learning.
Review: Missing Parts!! - I ordered the kit of 10 for a class project. I made kits of all the parts and distributed to students only to realize after that the kit didn't come with any of the metal axles needed for assembly. Very frustrating! I returned the first kit and ordered a replacement kit which did have all of the parts.

## Features

- Hands-On Physics Project, Mouse Trap Car Kit: Students build mousetrap-powered cars and race them to test how stored energy converts to motion. Designed for classrooms, after-school programs, middle school physics, and STEM clubs.

## Questions & Answers

**Q: How long does it take to assemble?**
A: Kids ages 8 and up can build the mousetrap car on their own in 30 minutes or less, but make sure to save time to experiment and play!

**Q: Is it safe for kids?**
A: Yes, the assembled car is safe for kids to use as instructed. It's recommended to remove the mousetrap trigger with pliers so kids cannot arm the trap.

**Q: Where is the kit made?**
A: The kit is made in China, but designed and distributed by STEM Inventions LLC, a small US-based business owned and operated by a former project-based educator.

Needs better directions. Assembly was confusing. Once built the kids had fun but it took awhile
