[1.8] Make a protective plastic 'skin' for your calculator

If you use your calculator in a contaminating environment, or just while you're eating pizza, this tip
offers some measure of protection.
Wrap the calculator with plastic wrap. Heat it with a hair dryer (blow dryer) on the medium setting, just
until the plastic softens and conforms to the keys. Don't over-do it - the LCD display can be
permanently damaged by too much heat.
