Brain teasers for incubation

1. Triangle of coins
Move three coins to turn the triangle upside down.

2. Animals in boxes
Draw just two squares to provide each pig with its own enclosure.

3. Match stick cow
Move two match sticks to make the cow face the other way. You can try this one on your friends using real match sticks; leave it on the bar or the dinner table and let them incubate it too.
