BV500: Sister Proof?

Another new piece of gear I purchased for the John Muir Trail is the Bear Vault 500. A Bear canister is a mandatory item for storing food while backpacking the JMT. The system to open it is much like a childproof pill bottle to prevent bears or other critters from snatching your food.

My sister, Rachel, was curious to try it out. I think she proved the effectiveness of the canister!
