In this engineering party game, children ages 6+ play the role of material testers! Players draw secret property cards and then take turns drafting objects from the box which they predict which match the properties on their cards. Then the testing begins! Players reveal their cards and together the group performs simple tests to see who was the best guesser. Points are earned for matching property cards, and the player with the most points wins! Note: The box itself acts as a testing kit, as well as containing 14 objects to be used in the drafting round. Players can also customize with addition of their own objects. —description from the publisher
