Crack it open!



Geology doesn’t get more exciting than breaking open rocks and finding crystal treasures! This hands-on kit includes premium geodes, safety goggles, a geode display stand, magnifying glass and learning guide. (Winners will require a household hammer.)

To be in the running for a geode kit from UGames (www.ugames.com.au), solve this riddle and send us a poem about the answer.
