This review is from : Activity Rock Kit
Helps foster curiosity in petrology . We also recently bought a similar set at our local natural history museum's gift shop. The magnetite isn't very strong, in fact it barely attracted the paperclip included with the rock. But it worked exceptionally well with some small pins (that I use for sewing), succeeding in holding two dangling pins end to end. I think you'll be disappointed if you expect it to be as strong as a conventional magnet.
As for the pumice, it floated as promised.
Initially I had difficulty getting the quartz to spark because I wasn't striking hard enough. Once I did, it worked really well, especially with successive hits because it actually illuminated the rock. Disappointingly, one of the rocks isn't as smooth as before making me not sure how long this "trick" will last; however, at the same time, it actually illustrates the idea of erosion.
I haven't tried the dolomite stone yet because I'm not sure exactly what it's teaching. I'd like to read up a bit on it first.
I purchased this for my 5 1/2 and 2 1/2 year-olds and gave them a small transparent container in which to store these rocks and a geode. Once all this rain stops, I'm planning to take them rock hunting to add to their collection. Even now, they really enjoy looking at them, especially my younger one. We have also been reading the books, Rocks, Rocks, Rocks Rocks! Rocks! Rocks! and Let's Read and Find OutLet's Go Rock Collecting (Let'S-Read-And-Find-Out Science. Stage 2).

Activity Rock Kit Reviews
Smaller version of kit- disappointed . We bought a slightly smaller version of this kit at a museum shop, and were disappointed with it. My son was very excited about the possibilities, but upon opening the kit the magnetic rock did not work at all and one of the quartz crystals broke into shards within the first 5 minutes of him trying to make the sparks (and he isn't that strong!). After one week no crystals formed on the dolomite... but the floating rock floated. 1 out of 4 worked as stated, not a good ratio.
Disappointing!
