Chronicle Flask - I love my naturally-occurring pesticide
Have a little fun with your chemophobic friends and colleagues by reminding them of the true nature of one of humankind's favourite psychoactive drugs.
This 11 oz (313 ml) mug has a diagram of a caffeine molecule with the message "I my naturally-occurring pesticide" on one side, and the logo of the award-winning Chronicle Flask blog on the other.
The handle and the inside of the mug are black, all the better to resist those pesky tea and coffee stains. Drink up!
