100 Ping Pong Ball Smoke Bomb

This is a 100 ping pong ball smoke bomb that my friend and I made. This is how we did it.-------------------------------------- We first cut up 100 ping pong balls by doing 50 each. We then put all of the pieces into a sheet of tin foil, and added more layers of tin foil until bits of the ping pong balls were no longer poking out. A hole was then made in the bottom of the tin foil so that we were able to see the ping pong balls. (No need for a fuse). We then lighted this hole until the ping pong balls were on fire and then put it down (fire side down). The smoke then just escapes from underneath creating a smoke bomb with lots and lots of smoke. Lots of the smoke actually travels along the ground because it's in a wind tunnel but when you see the open air, you can see how much smoke their is. Happy Watching.

Ten Amazing Brain Facts ...DOnt surprise!

What part of you is only 1% to 3% of your body's mass, yet uses 20% of all the oxygen you breathe? Your brain! Here are ten more brain facts.

- Your brain needs a continuous supply of oxygen. A 10 minute loss of oxygen will usually cause significant neural damage. Cold can lengthen this time, which is why cold-water drowning victims have been revived after as nuch as 40 minutes - without brain damage.

- Your brain uses a fifth of all your blood. It needs it to keep up with the heavy metabolic demands of its neurons. It needs not only the glucose that is delivered, but of course, the oxygen.

- Your brain feels no pain. There are no nerves that register pain within the brain itself. Because of this, neurosurgeons can probe the brain while a patient is conscious (what fun!). By doing this, they can use feedback from the patient to identify important regions, such as those used for speech, or visualization.

- The cerebellum is sometimes called the "little brain," and weighs about 150 grams (a little over five ounces). Found at the lower back side of your brain, you need your cerebellum to maintain posture, to walk, and to perform any coordinated movements. It may also play a role in your sense of smell.

- The human brain weighs an average of a little over three pounds, or 1.4 kilograms. Albert Einstein's brain may have been smaller than yours, because he was smaller than average. There is a general correlation between body size and the size of our brains.

- An elephant's brain is huge - about six times as large as a human brain. However, in relation to body size, humans have the largest brain of all the animals, averaging about 2% of body weight. A cat's brain? It weighs about one ounce, a little over 1% of body weight.

- There are about 100,000 miles of blood vessels in the brain. If they were stretched out (there's a nice thought!) they would circle the earth more than four times.

- If you have an average sized brain, you have about 100 billion neurons up there. You'll be happy about that after reading the next item.

- Approximately 85,000 neocortical neurons are lost each day in your brain. Fortunately, his goes unnoticed due to the built-in redundancies and the fact that even after three years this loss adds up to less than 1% of the total. Oh, and look at the next item.

- Recent research proves that your brain continues to produce new neurons throughout your life. It also proves that it does so in response to stimulation (do those brainpower exercises). Scientists refer to this as brain plasticity or neuro-plasticity. You may find this one the most encouraging of these brain facts.

Easy Invention Ideas - How To Have Them

Want easy invention ideas? Dreaming up new products and inventions is fun, and it can be easy too. Try the following two techniques and soon you'll have a list of new ideas.

Easy Invention Ideas - Start With What's There

One of the easiest ways to create new ideas for inventions is to look at what already exists and find a way to make it better. You can start with things in your own home. These may even be the most marketable ideas - consider how many new kitchen gadgets are sold every year.

Look at the toaster, for example. How could it be improved, replaced, or the need for it eliminated? You could eliminate the need for it if you designed a stove with a toaster built into it. You could replace it with something like a waffle iron. You could improve it by making it faster, perhaps with a combination toasting element and microwave heater.

Look around the room and pick out any item you see. Imagine how it would be if it was bigger, smaller, faster, slower, or different in some way. As I write this, I am looking at a calculator. I would like to be able to talk to it. I could just say, "Mortgage payment, $140,000 loan, fifteen-year amortization, six point five percent interest rate," and it would announce, "$1219.56 per month." With all the latest voice-recognition technology out there, this is possible.

Want an easy way to create a lot of new invention ideas fast? Make a list of everything in your house. Then work your way down the list, thinking of some way to improve or re-invent each item. If nothing comes to mind, move on to the next item on the list after a minute or two.

Easy Invention Ideas - Use What Irritates

What irritates you? Do you hate the way the ice builds up on the edge of your roof? Do you get annoyed with the way the dog slops his water and food all over the kitchen floor? Annoyances and irritating things are not just problems, but excellent opportunities for easy invention ideas.

Suppose you are tired of burning your tongue on hot coffee. What could save you from this irritation? Perhaps a cup with a built-in thermometer that shows green once the coffee has cooled enough? Maybe a cooling device to set a coffee cup in, like a small fan that blows across the coffee when the cup is set on the device?

Annoyed with the necessity of brushing your teeth so often? Maybe there is a Teflon-like coating that could be applied, so food wouldn't stick. If it was anti-bacterial as well, you might avoid plaque even after days without brushing.

Looking at what is around you and imagining small or large improvements is easy. It also isn't too difficult to train yourself to look at problems as opportunities. There are dozens of other techniques that will give you easy invention ideas, but start with these two simple ones and you can have a hundred new ideas today.
