5. Research Lab
"Research Lab" is a board game created by Sheldon where the tagline reads, "The physics is theoretical, but the fun is real," and was revealed on "The Guitarist Amplification" (Season 3, Episode 7).
How To Play:
The board features spaces that are configured into the shape of the Bohr model of the atom.
To make a move, you roll the dice to move onto a space, where you can you draw a card that benefits you, hurts you, or hurts other players.
These hurtful outcomes include disasters such as a nuclear meltdown, industrial accident, and/or a loss of a retina by staring into a helium-argon laser. Benefits include a renewal of a Department of Defense research grant.
