1. Alarm Clocks
Does your roommate's phone alarm sound through the wall and drive you crazy? Call them. It will turn the alarm off. Wait for them to answer and they won't even miss work.
2. Plane Tickets
Buy your plane tickets in the middle of the week to save $100 or more. Ticket vendors jack up the prices on the weekend to trap vacationers who make impulse ticket purchases.
3. Bagel Holder
Here's a new use for your ancient CD-rom holder! You can take that useless old piece of plastic and repurpose it as a convenient sandwich holder.
4. Unplug It
Before you leave for work or class, unplug everything. Even when electronic devices are off they suck up energy. Pulling the plug can cut up to 10% off of your energy bill.
5. Wasp Spray
Work in a shady area? The cops recommend keeping a can of wasp spray on your desk. It will deter would-be attackers from up to 20 feet away and won't blind everyone else in the room too.
6. White Boards
Accidentally wrote on the white board with permanent marker? Scribble over it with dry erase marker and it will erase right off.
7. Grocery Bags
Don't let those plastic handles dig into your fingers. Thread a small, hard item through the handles and hold that instead.
Place a muffin tin liner on the bottom of your popsicle. It will catch the drips and keep your fingers from getting sticky.
9. Grilled Cheese
Put bread and cheese in the toaster sideways. It makes a DIY toaster oven that makes great, crunchy grilled cheese sandwiches.
10. Dryer Sheets
Put a dryer sheet in your pocket next time you go hiking or camping. It will keep the mosquitoes away from you.
