Back in 2001, Simon Bradshaw and his colleagues published a tongue-in-cheek article in Plotka analyzing the utility of a chocolate teapot. They were inspired by the phrase (common in the UK) that something is as "useful as a chocolate teapot." Their conclusion was that chocolate teapots are indeed not very useful since they leak everywhere, and therefore they "serve as an excellent baseline of uselessness against which to compare other, similarly dysfunctional, items."
The article became a minor classic of scientific humor. (Yeah, science humor tends to be a bit nerdy) and was replicated by other researchers.
More recently, the Naked Scientists (authors of Crisp Packet Fireworks) decided that the problem was that the teapot was too thin. If you make the chocolate thick enough, it'll hold the hot water and brew tea. But how thick? Two centimeters proved to be enough. They note:
When chocolate melts it doesn't become totally liquid immediately, it remains quite viscous. Unless you apply a fairly large force to the melted chocolate, it seems to sit there. Chocolate is also mostly made of fat, which is a good thermal insulator (whales use blubber as a form of insulation). This means that the molten chocolate near the hot water protects the less molten chocolate below it, insulating it from the heat of the water. Also, it takes a significant amount of energy to melt chocolate, so it will take a significant amount of time to move heat into the solid chocolate, thus slowing its melting.
The main structural design defects were the lid, which melted, and the spout, which collapsed after the tea was poured.
Can you explain how one pretzel in a bag of pretzel sticks would end up white? I can't.
Via J-Walk, who offers this theory: "In the pretzel cooking factory, a new employee found an uncooked pretzel on the floor and tossed it into the pot soon before the others were done. Little did he/she know that you shouldn't do that."

While others are off at church on a Sunday, why not stay in and have a pagan breakfast celebration, with Baconhenge.
Let Baconhenge be the site of your seasonal celebration! Let bacon stand in for the sacrificed Year King, French toast for the Grain Goddess, the eggs in the frittata for the Cosmic Egg, and the vegetables for the bountiful Earth on which we live.
Ingredients include 12 pieces of french toast, a pound of bacon, a potato, onion, mushrooms, and a dozen eggs. I can't wait to try it! (via J-Walk)
For no perceptible reason, I woke up this morning thinking about Bonomo's Turkish Taffy, a childhood treat I have not pondered in decades. After waxing nostalgic (despite Nostalgic's objections to being waxed), I began to wonder:
If this candy were still being manufactured today, would its allusively Muslim name doom it?
Here's part of the reason why we're a nation of fatties today. "Lose weight the hard way? No thanks! I'll just compress my flab and strap it in with manmade materials!"
And why is it that the only women ever shown in girdle ads are already so trim and underweight that they aren't the real customers?
