Creating a tornado science fair project has been quite popular at science fairs. Of course, it isn't possible to create a life-sized tornado for obvious reasons! However, miniaturized versions may be created using simple models like the one about to be demonstrated. It is to be remembered that proportions matter a lot, while creating the models. Therefore, these exact proportions need to be followed. The following is possibly the simplest tornado science fair project that can be made with daily household materials. This experiment demonstrates the formation of the eye of the tornado - the central zone of calmness known as the vortex - within ordinary bottles.

Drill Power Tools

The tornado science fair project requires simple ingredients:
- Two large bottles - the larger the better. Soft drink bottles made of plastic are recommended.
- Water colored using food coloring. The lighter the color is, better the demonstration will be. Glitter dust or confetti result in a dazzling display.
- A drill.
- Duct tape and silicon caulking.
- A steadily spinning surface, an old record player if possible.

Drill Power Tools

The apparatus can be set up quite easily. The first step of tornado science fair project is to make half-inch wide holes at the center of the caps. These caps may then be joined together using the silicon caulking, keeping the holes connected. The bottles may be filled with the colored water now. The second step of the tornado science fair project is to attach each end of this double cap to each bottle. Finally, the two caps may be firmly fastened using the duct tape. The entire apparatus takes a shape and form similar to that of an hourglass.

Now, the entire apparatus of the tornado science fair project may be placed upside down, the bottle with the water being at the top, on the spinning surface. It will be observed that as the water slowly drains out to the lower bottle, a vortex is formed in the midst of the spinning water. This vortex is similar to the structure of the vortex formed inside a tornado.

Precautions to be taken during this tornado science fair project are few, but important. The joints must be made perfectly airtight, so that there is no leakage of water and air bubbles don't enter the bottles. Moreover, the spinning surface must have a steady motion. Otherwise, the entire rhythm of the tornado would be disrupted. The steps are few; however, are important in a tornado science fair project.

The project, as it stands, is a very simple, elegant, and elementary science fair project that judges see all of the time. What you must do in order to stand out is to make this project a little bit different than everyone else's science fair project. The fact is, with a project like this, you won't get a really stunning A+ grade simply because this project didn't involve too much individual thinking. However, by taking this model as a start and exploring some related concept or by looking at some specific aspect of the model, you can really earn a fantastic grade, and maybe even win the science fair with this simple tornado science fair project.

Christmas Sales Bosch DDS181-02 18-Volt Compact Tough Drill Driver with 2 1.5Ah Batteries Overview

Ready for heavy-duty drilling applications in materials ranging from wood to metal, the small yet powerful Bosch DDS181-02 Compact Tough 18-volt lithium-ion 1/2-inch drill/driver's 7-inch head length is the smallest in its class, yet it delivers top performance. It works with all Bosch 18-volt lithium-ion batteries, and this kit includes two Slim Pack 1.5 Ah HC (high-capacity) batteries. They provide up to 50 percent more runtime over standard lithium-ion batteries and include an electronic battery fuel gauge to ensure you have enough power for the job.

Compact and lightweight with included Slim Pack HC battery (view larger).

Fast Speeds, High Torque, and Durable Construction

The DDS181-02 has two optimized speeds--one ideal for high-torque applications (0-500 RPM) and one ideal for high-speed applications (0-1,700 RPM)--and it provides a maximum of 600 inch-pounds of torque. The 4-pole open frame motor and newly developed gearbox provide exceptional power for such a compact drill/driver. The 18+1 clutch settings included in this Compact Tough model and a variable-speed trigger help you match the best speed to the job, so you can achieve precise results. It can drive 500 screws per charge using the BAT619G 3.0 Ah HC battery (not included).

Balanced Design and Easy Bit Changes

The ergonomically designed handle and soft-grip wrapped housing offer a comfortable fit for extended working time. The DDS181-02 comes complete with a single-sleeve 1/2-inch auto-lock chuck for one-handed bit changes, as well as increased drill-bit capacity for versatility. And for even greater convenience, LEDs provide illumination when you are working in dark or enclosed areas.

Flexible Power System

In addition to the 1.5 Ah HC lithium batteries included in this kit, this drill/driver can be used with Bosch's batteries from its 18-volt line--including the 1.3 Ah Slim Pack battery (model BAT609), the 2.6 Ah Fat Pack battery (model BAT618), and the 3.0 Ah HC Fat Pack battery (model BAT619G). If you're looking for a lightweight option, the Slim Pack is the perfect choice. If longer runtime is what you need, the Fat Pack will do the job.

ProVantage Guarantee

The DDS181-02 comes with the ProVantage three-year protection plan, which guarantees two years of battery protection and one year of tool protection. Under this plan, you can receive two years of free battery replacements, tool replacement for one year, and a free tool repair package for the second and third years.
