BUBBLE WRAP. Engineers Alfred Fielding and Marc Chavannes came up the idea for bubble wrap while working on a new type of textured wallpaper in 1957. By sealing two shower curtains together, they trapped a layer of bubbles.
Immigration and Customs Enforcement. Special agents at Immigration and Customs Enforcement, the largest investigative agency in Homeland Security, are classified as criminal investigators. They start at GL-7 with an annual base salary range of $33,829 to $42,055, or GL-9 with an annual base salary of $42,948 to $55,413.
Some local law enforcement officers are very well compensated, depending on their assignment. At the medium-sized police department where I used to work, the base pay for a non-supervisory police officer ranges from about $60,000 to $80,000 per year, reaching the top pay step after seven years.
