There are vending machines Tokyo, Japan where you can purchase a can insect snacks. The menu includes dried tarantula and scorpions. However, not everyone is excited the idea of insects as food. An Israeli insect farmer, Dror Tamir, says there is a "yuck factor" to the thought eating insects. He said people will get used to the idea and will find insects tasty.
