A couple years ago, I wrote about a series of anatomically accurate jigsaw puzzles that fit together into one giant cross-section model of the human body. If you (or your science-minded kid) liked those puzzles, you’ll be glad to know they have another series of them that focuses in on five specific parts of the body:

• The Human Brain ($24)
• The Human Eye ($24)
• The Human Feet ($24)
• The Human Hands ($24)
• The Human Heart ($24)

Like the previous set, these educational puzzles feature stunning artwork by Johns Hopkins University-certified medical illustrator Mesa Schumacher. As you build them, you’ll marvel at all the details and the complex, dynamic nature of these biological machines we live in.

You can buy the puzzles individually as listed above, or you can get the full bundle for $100 and save twenty bucks.
