In today's episode Maddie is on the move. She finds out how things that we use every day are brought to us on big ships and moved around the country in shipping containers on trains. She visits a shipping port and uses a special camera attached to the shipping containers to find out what happens when they are lifted on a big crane. Next, Maddie visits a bubble packaging factory and uses a special slow-motion camera to show how the air gets trapped inside the bubble packaging when it is made.
