It's 11:00 pm, and you just came home from a long night out. You have to go up stairs, brush your teeth, change into your pjs, and climb into bed without waking your children. Well you don't have to worry because now there is the light up rug, which will light up with each step you take. The light that the rug emits is very soft, and it will light up in response to your weight.

El Nino class response

Do you remember Hurricane Katrina? Well it was caused by a weather patter called El Nino, which occurs once every three to seven years.

This is called El Nino. this effects the fishing industry because the fish follows the cooler water because the cold water has more nutrients.

But, then the typewriters gave way to computers, which lets you see what you write before you print and you can correct it with out wasting paper. Now, not only does computers have word processing, it also has spreadsheets, slideshows, video cameras, music players, video players, CD makers, and of course, the Internet. Then, computers were almost obsolete. Now, almost every household has one.
