the light did not come on. I tried flipping the switch a few times to adjust to a different color but nothing comes on. My first thought was the light went out and need to replace it...didn't knokw they were so expensive to change. How do i know what kind of light I have ??
Place a thermometer in each container of water to track the temperature change. Does the angle of the box toward the sun make a difference? What if you use a longer piece of tubing and make more loops? The warmer the water coming out, the more heat it's absorbing from the sun. If ...
and so i actually had to really figure out how everything was gonna work. i had to do all the math and computation to understand how the circuit was actually gonna function. things change. this is one of the og prototypes for one of the first pool sculptures. i like to keep it around...
With natural daylight, the changes happen subtly throughout the day, so initial colour change isn’t always apparent. However, when you’re concentrating and trying to paint a subject, you are battling against the perceived colours that keep changing! This is why inMonet’s Haystack serieshe w...
One way to cut back on car use is to try public transportation to save money. Biking and walking to work, if options, are ways to save on money. They require a change of habits and trying new things. But over time the health and savings benefits might make them a welcome change of ...
It takes as much energy to evaporate a cc of water as it does to raise it from the freezing point to the boiling point. It takes a TREMENDOUS amount of energy to evaporate water so any small amount will pull energy from the environment…or from your body…to change the state of liquid...
The coffee table is called the Wave, and it uses LED lights to interact with whatever is placed on or near the table's surface. LEDs, or light emitting diodes, are bright white lights that don't use a filament (the little wire inside a bulb) like incandescent light bulbs. Instead, the...
For instance, if you leave an 60-watt light bulb on for 24 hours, the energy usage will be calculated as follows: 60 watts x 24 hours = 1,440 watt-hours (1.44 kilowatt-hours) (For a complete guide to watts and other electricity terms, check out: Understanding Solar Power Electricity ...

This has led to technological inventions from housing to space-probes that (crash) land on a different planet. Yet, when it comes to living organisms, our control over their behaviors has only been partial. Initial works have been done using small molecules to activate or inhibit (...
