Hi,
When you feel bored, here are some things you can do..

> THINGS YOU CAN DO WITH ABSOLUTELY NOTHING

1. Blink wildly and then close your eyes really tight for an interesting light show:
Amusement Potential: 1-5 minutes
See a variety of blobs, stars and flashes. Try to make out shapes and see if your subconscious is trying to send you a message.
2. See how long you can hold a note:
Amusement Potential: 4-20 minutes
Not that much fun, but it sure passes the time. Play with a friend, or try to beat your own personal best. Inhale deeply and then try and make a noise for as long as you can. Earn extra points for making your partner laugh or ending on an amusing note.
3. Try to not think about penguins:
Amusement Potential: 1-5 minutes
This is especially hard, because by trying too much, you remember what you are trying to avoid thinking of. If you try too little, you end up thinking about penguins anyway.
4. Use your secret mind power:
Amusement Potential: 5-10 minutes
Pick a passer by and try to use your mind power to command them to do something, like drop their bag or knock into someone. The law of averages dictates that sooner or later one of your mind commands will come true, so you can convince yourself that you really have super human powers and waste even more time trying them out :P .
5. Pretend you’re a robot:
Amusement Potential: 1-3 minutes
Walk down the street with mechanical movements, adding ‘zzzzzt’ sounds with each motion. Pretending to have a motor broken in, say, your left hand, can add at least 30 seconds more entertainment. Though of course if you care about what the others passing by, will think of you, better avoid this :P .
6. Scratch yourself:
Amusement Potential: 1-3 minutes
Go ahead, scratch yourself now. Even if nothing itches, go ahead. Doesn’t that feel pretty good?
7. Repeat the same word over and over until it loses its meaning:
Amusement Potential: 1-3 minutes
Pick a random word out of a magazine and say it aloud to yourself until it becomes a meaningless set of noises.
8. Hurt yourself:
Amusement Potential: 1-3 minutes
What is pain? Why is it unpleasant? There’s nothing physical about it – it’s all in your mind. Plus, after pinching yourself for a while, boredom will seem nice next to being in pain.
9. Try to swallow your tongue:
Amusement Potential: 1-3 minutes
There’s not much to say about this one. It is possible, but really stupid.
10. Pretend to be a car:
Amusement Potential: 1-3 minutes
Make appropriate revving noises in your head as you walk along and add a racing commentary as you pass strangers in the street. Use blinking eyes as indicators for extra authenticity.
11. Get yourself as nauseated as possible:
Amusement Potential: 5-10 minutes
Best achieved by looking straight up and spinning around. Try to be so dizzy you can’t even stand up. This is also entertaining due to the “makes boredom seem a lot better” effect.
12. Make a low buzzing noise:
Amusement Potential: 15-30 minutes
Hours of fun in libraries (and in boring classes)! Keeping a totally straight face and looking nonchalant, make a low pitch humming/buzzing noise and see who reacts.
13. If none of the above are good enough, do what i am doing right now, write a stupid post and bore others as much as you can :P .
