How to Heat Your Room for 15 Cents a Day Wanting to cut costs on the energy bill, especially now that temperatures are dropping for the season? Economics may be one reason to seek more sustainable energy sources, but this inventive way to heat the house is also purely fascinating. Journalist, YouTuber, and boat owner Dylan Winter created his DIY heater using tea lights and placed inside a bread tin and covered with two ceramic flowerpots. This creative system uses the scientific principles of convection heat transfer and, according to Winter, can heat his home for around 8 hours a day. The tea lights are first put into a bread loaf tin and covered with a small upside-down flower pot. The hole in the top of the upside-down pot is covered with the metal casing leftover from one of the tea lights. This system works because the candles produce gases full of heated particles that are captured and channeled through the pots. One does not need a huge amount of money to invest in this economical heating method, either.
Chemical Reaction Games For Kids & Learning About Combustion In a chemical reaction a reactant is consumed during a reaction while a product is formed as a result. In this game two examples of chemical reactions are highlighted: combustion and gasification. In both cases a hydrocarbon (such as oil, coal or wood) and oxygen are the reactants, while the products vary depending on the process and amount of oxygen. Any product of a chemical reaction that is not the intended product of the reaction is a by-product. There are two types of combustion: complete and incomplete. Gasification converts hydrocarbons by reacting them at high temperatures with a controlled amount of oxygen and steam.
DIY: How to Make Endless Hot Water Without Electricity Using some recycled parts and a small rocket stove you can heat and pump all the hot water you will ever need without power. This ingenious technique utilizes thermal siphon pumping to move the freshly heated water into the reservoir.

amazon How to make a rocket with sugar and kitty litter Got some powdered sugar and kitty litter just lying around? Sure, there are some more practical uses for both of those things, but let's add some potassium nitrate to the mix and blow it all sky-high. [optional caption text here] Image: [name here]/Shutterstock There's a special place in YouTuber Grant Thompson aka the King of Random's heart for rockets made from innocuous, everyday objects. But what if you could use some plain old powdered sugar and a little bit of potassium nitrate to create a homemade pyrotechnic mixture that can launch a rocket over 700 metres (2,300 feet) into the air? Watch the video above to find out how you can construct this awesome little homemade rocket, complete with a built-in time delay and a parachute ejection charge.
Colorful Convection Currents Fill two bottles with warm water from the tap and the other two bottles with cold water. Use food coloring or the Fizzers coloring tablets to color the warm water yellow and the cold water blue. Each bottle must be filled to the brim with water. Hot over cold: Place the index card or old playing card over the mouth of one of the warm water bottles. Hold the card in place as you turn the bottle upside down and rest it on top of one of the cold water bottles. The bottles should be positioned so that they are mouth to mouth with the card separating the two liquids. If you are using our Split Demo Tank, follow these directions: Make sure that the tank divider is firmly in place. Hot air balloons rise because warm air is lighter than cold air. The movement of warm and cold water inside the bottles (or tank) is referred to as the convection current. What are the results of temperature inversion? More Weather Experiments

20 Best Camping Gadgets For The Great Outdoors While the rewards of time spent in the wilderness are nearly priceless, not everyone possesses the desire or the means to truly rough it in for an extended period of time. And while Emerson, Thoreau, and Kerouac may have differed in opinion, we believe holding on to some semblance of our tech-driven lives helps us maintain some sanity and safety in the great outdoors; no one wants to quit cold turkey. Now, we’re not suggesting a direct transference of your home entertainment system to the nearest campsite, but we do want to shed light on some perks that even the most adventurous outdoorsmen may receive from a little tech assistance. And that’s the goal here: to not remove the stars from your vision but to make them more visible, to not prevent you from enjoying time alone with nature but provide you with a hot meal when the day is done, to light up the night without worry, and maybe even document a few moments as well.

Building a Simple Kirlian Photography Device The Kirlian device we are building uses a HV transformer. It is battery powered, but don't let that lull you into a false sense of safety. The Kirlian device generates pulses of high voltage that can provide a nasty shock. Still an advantage of being battery powered is portability. In addition we will build a transparent electrode that allows one to use a standard camera (with bulb setting) to capture Kirlian images. The schematic is shown in Figure 2. Figure 2 If the photo batteries are not available you may want to try wiring 10 or more 9-volt batteries in series. The capacitors C1-C4 are wired in parallel as shown in Figure 2. The transformer T1 is a high voltage auto-transformer. Figure 3 The toggle switch SW1 is a single pole double throw "momentary" contact. The switch is important and must be wired correctly to obtain maximum benefit. To mount the switch to the board a metal battery clip (9-volt) is used, see parts list.
