NATIONAL GEOGRAPHIC Break Open 5 Jumbo Geodes - Earth Science Kit with 5 Premium, 8-10 cm Geodes with Crystals, Goggles, Learning Guide & Display Stands, Science Gifts, Fun Stuff for Kids

My son loved it he was amazes at how big they are

Bought as a joint Christmas present for my three kids - one solid, one very dull stone and all white.Realise you can’t know what you’ll get, but we were a bit underwhelmed and disappointed, especially since it felt like a lot of money to spend.

I bought these as a fun project to do with my kids and they did not disappoint! Four of the five rocks were beautiful geodes, one was just a nodule. The nodule was extremly hard to crack... Nothing my husband, a metal punch, and a handheld sledge couldn't handle! We will polish the inside for a nicer look. The other rocks were realitively easy to open... My seven year old was even able to crack one! They recommend the sock method, but if you want nice clean breaks I would not go that route. All in all, I am very satisfied with the product we received and will buy again!

Was disappointed to see that one of the geodes is broken into many pieces. An expensive kit, and should be packaged better to avoid breaking during shipment. Though the bag of rocks was opened so perhaps someone returned this set already.

a mia nipote a cui l'ho regalato è piaciuto moltissimo ; ci siamo divertiti ad aprirli insieme e poi i geodi erano molto carini ; unica pecca che li avrei voluti più vari come finitura

RAS reçu en temps et en heure.

The kids were really turned on by the crystals sudden appearance. Lovely to watch.
