Great but quite small

Provided some hours of learning and play and created some interesting discussion about batteries. The down side was that the ingredients to make only two batteries were provided, expected to last one hour each. When they run out the toy will loose its magic.

Bought in early April 2020 for a snow day. Just brought out today for the kids to put together. Does not work. Followed instructions carefully, but just doesn't go. Appears to be a design fault.

Does not work and is smaller then it appears. Would not give as gift. Shouldn’t cost more the $5.
Hi.I gave it as a gift so really don't know if it's a great gift or not. But it sure seems like a fun item with the added 'educational' component. Great price point, too.
I bought this for technical Knowledge.Very interesting.Quality product.
Bought this for a scientific minded 10 year old. He was able to put it together easily but when it came to adding the salt water it does not work. We have tried and could not get it to work and also it is very small. He was most disappointed with this present.
