The Unstable Eggs are a series of blind balancing puzzles. Your goal is to get each egg to stand up straight, but all they want to do is fall over. Careful listening skills and even an astute sense of touch are required to figure out the secrets within! Each color offers a unique challenge with a simple, but not necessarily easy mechanism within.
The carton set is packaged in a specially branded paper-pulp storage egg carton complete with 6 eggs.
