Chemistry Lab Perform over 100 safety tested experiments with the Chemistry Lab and its easy to use and informative Instruction Booklet. This very popular chemistry set contains a spirit burner, and 22 chemicals - twice as many as our other sets. Chemistry sets aren't as spectacular as they used to be - due to health / safety / terrorism concerns - but this is the best one we know of. £24.45

Motorised Solar System and Planetarium Light and motion give this model a dynamic way to demonstrate the workings of the solar system. We like the fact that the planets orbit the correct way (the same way that Earth rotates on its axis) - incredibly, half of the others we've seen go the wrong way. It also has a 'planetarium' (star projector) which is adequate for learning the constellations, but don't expect sharp, focussed images. £22.50

Explorer 2 Electronics Kit The kit is for use in the home or the classroom and could be used to enhance the understanding of Key Stage 3 and 4 electronics. Easy to assemble projects (900) using press-studs, no soldering. Many varied components make this a highly versatile kit. Turn your computer into an oscilloscope and study the waveforms of the sounds you produce. £46.00

Rainbow Spectrum Kit This kit - produced by Curious Minds - enables you to create spectra in the absence of bright sunlight, using a glass lens together with a prism or diffraction grating, and a white light. The instruction booklet contains several experiments, and explains enough science to understand the results. Newton would have been delighted! £14.99

FunFlyStick Wizards of all ages have now an incredible opportunity to get a real levitation wand of their own. Five special flying toys are included in the set. Mesmerizing levitation is captivating for everyone observing. Enjoy levitating incredible metallic-looking shapes and learn physics in the process without even realizing it! Illustrated full-color Magic Wand Manual provided with the set offers tons of tips and tricks for becoming a better wizard. £22.95

Solar Radiometer Sunlight, or heat from a flame, or even your hand, can make the vanes rotate. If the radiation is strong enough, according to one source, the vanes can rotate at up to 3,000 times/minute. How do they know this? Well, I have found a method, using a laser pointer, a light-dependent resistor (LDR), a battery, and two loudspeakers and oscillator. Shine the laser through the radiometer, onto the LDR, such that the vanes interrupt it as they rotate. The LDR connects to the speaker and battery in series. Bring a bright lamp close to the radiometer; as the vanes rotate faster you can hear a low hum from the speaker, rising in pitch. Compare this with the oscillator connected to its own speaker; you can get the same frequency from each, and read it off from the oscillator. Divide by 4 because the radiometer has 4 vanes, and you have the rotation speed.

Mirage Desktop 3D Hologram Maker Make a mirage appear - right before your eyes! Even the camera sees it. But you can't touch it! And neither will anyone else. Scientists call these amazing phenomena three-dimensional real images. Indeed, the illusions you can create are so brilliant, so alive with color and depth, they defy, yet demand, explanation. Never has the fine line between reality and perception been exposed with such startling clarity. Mirage faithfully reproduces every detail of the object you display within it. Take your laser pointer, and shine it on where the object appears to be (but isn't!). What happens?
