Headaches/Stains/Celery

Here are 3 different tips that don't belong together, other than that fact I think they are awesome.

1- Store your celery in aluminum foil to keep it fresher longer.
2- Cut a lime in half and rub it on your forehead to get rid of headaches. This should take the throbbing away.
3- Spray your Tupperware ( plastics)with non stick spray before adding anything tomato based. It will keep it from staining.
