Install Minecraft on school Chromebook

The title sums it up. School is boring, so I'm trying to find a way to install Minecraft on the school laptops (Chromebooks). I already installed Minecraft using a USB drive with the installer on it on one of the school windows computers in the computer lab, but I only get to enter that room for one period during the day. Minecraft recently released for the Chromebook, but it is much more difficult to do funnies on the school Chromebook because of how restricted and monitored they are. Linux cannot be installed through the settings and installing any browsers other than Chrome is finicky and has not worked for me as far as I know. How can I install Minecraft on the school Chromebook with a USB drive as a resource?
