Principle: Magnetism

Interaction: Children age 10-12

Cost: $100+ because table is complex with maze and good magnets are expensive

Durability: Hard to break material

Safety: Strong magnets swallowed are dangerous but can be avoided with monitoring and large pieces

Reflection: I think this game would be very fun. From personal experience I've played with magnets and witnessed a lot of kids seeing the effect of the positive and negative poles of the magnet. Children are natural at trying out extreme cases like seeing if magnets still attract each other between lots of objects. That's why I got inspired to design a table maze because it's a challenging obstacle that's also open to a lot of experimentation.
