It is all in the 2012 Waste Book report. There are 100 examples totaling nearly $19 billion of weird things the government is spending money to fund, including a robotic rodent designed to test the interaction between rattlesnakes and squirrels. Sen. Tom Coburn of Oklahoma said that $19 billion is basically a drop in the bucket to the overall $16 trillion spending but its gives an insight to what some people think is important spending.
There are some interesting things in the book like food we could be eating once we make it to Mars and $700,000 to a theater company so it could develop a musical about climate change and biodiversity. The list of stuff is interesting. I am sure some of it has logical reasons behind it, but it looks like some are just a little out there even for me!
