Fun Express DIY Steam Car Craft Kits Makes 10 - STEM Toys Science Kits for Kids Age 5-7 8-12 | Educational Engineering Building Kit for Boys | Hands-On Learning & Education Toys for Science Projects

Bought these for a camp group and they loved it! I ended up writing out my own instructions based on my trial run and they worked great. I would advise using a hot glue gun to adhere the wheels. The actual balloon part was a difficult concept for the group but I don’t blame the design for that.

Got these for our lesson about air in cub scouts. Fortunately not all of my kids showed up, because it only had half the car-shaped cutouts. Supposed to be two patterns, we only got one. Anyway, took some trial and error but we got them to move. Make sure the straws don't get squashed during assembly or blowing up; they won't move then!

Be Prepared to use a glue gun because everything needs to be glued even the wheels to the axle sticks. The hole in the axle is a little too loose on the pegs so the wheels will not stay on without glue. Also there are no instructions included so do a test build before attempting with a group of kids. The length of the straw that holds the axle stick is important.

The instructions that came with the kit were completely different from the picture. They didn't work at all.

Kids love these do them. Every year.
