This special paint can help create electrical circuits on almost any surface, and dries in under 15 minutes to become conductive. Electric Paint is like a liquid wire; it can act as a conductive adhesive, it can be used as a capacitive sensor, and it is suitable for application on a wide range of materials from fabric to wood to paper. Whether used to lead a class in painting circuits, cold solder components onto paper, or create a cardboard piano, this material is a quick and safe addition to your toolbox.

Use our Spectrometer for introducing students to principal types of spectra and determination of the wavelength and frequency of emitted light. It can also be used for quantitative spectrometric measurement of angle of prism and refractive index of the prism material. It is similar to a Student Spectrometer but it has enhanced features for obtaining better quantitative results. The Spectrometer consists of a heavy cast base and a pillar for collimator support. The telescope arm moves along a fixed circular plate 6″ (150 mm) Dia., graduated in degrees (0-360 x 1). This plate has a double-ended vernier for more accurate measurements. Fine adjustment is accomplished by using a knob while coarse adjustment can be done by hand. Both the collimator and the telescope are mounted with an axis adjustment system. The telescope has a 10X Ramsden eyepiece and is fitted with a cross hair reticle. Both the telescope and the collimator are fitted with coated achromatic objectives of 7″ (178 mm) focal length and 1.25″ (32 mm) Dia., providing light for a brighter and sharper image. The focusing is refined by a concealed rack and pinion. The collimator slit 0.25″ (6 mm) long is specially designed for retention of initial accuracy during the life of the instrument. The prism table 3″ (75 mm) Dia. is held with the help of a clamping screw which enables the table to be rotated in any direction. This item has lines and concentric rings marked to assist in positioning the prism in relation to leveled screws. It is fitted with a diffraction grating holder of aperture 1″ (25 mm) x 1″ (25 mm) and a clamp for holding prisms up to 1.5″ (38 mm) high. The Spectrometer comes with a prism and a diffraction grating.
• Comes with an instruction manual
• Includes prism and diffraction grating

This apparatus uses modern technology to completely update the Ripple Tank concept. It provides a compact and elegant method of showing the wave phenomena of diffraction, refraction, reflection, and interference, with none of the usual problems. The tank is 4″ (100 mm) square and is supported on a base which provides the wave generator and lighting. Images of the water waves produced are projected upwards onto a frosted screen, which is viewed from above. The white light source can be switched between constant illumination and strobe to give either moving or frozen images on the screen. In the strobe mode, the light source is synchronized to the wave generator so that perfectly static patterns are displayed. The wave frequency can be varied, giving wavelengths in the tank ranging from several cm to a few mm.
Specifications:
• 4″ (100 mm) square
• Base that provides the wave
• 3 Acrylic shapes for refraction
• 3 Aluminum plates for reflection
• 3 Dippers for plane and circular
• Wave generation
• Full instructions
• Power adapter

Mess-free magnetic field study means there is no need to clean up iron filings. The clear cube is filled with iron filings suspended in a solution, which make it possible to view magnetic field patterns easily by adding a magnet into the center of the cube (magnet is included). The patterns can be observed from all angles and easily manipulated with other magnets from the outside of the cube. The clear acrylic material also allows for overhead projection for whole groups to view.

These one-of-a-kind tops, called Tippe Tops, have a smooth, mushroom-like shape. The tops will right themselves when pushed onto their sides. When spun, they will rotate and slowly turn themselves upside down to spin onto their ‘stems,’ due to their offset centers of mass. This seemingly simple ‘toy’ packs a big scientific punch; use it to explain concepts such as moment of inertia, angular momentum, rotational force, gravity, and friction.

How many breaths does it take to fill up an 2.4 m (8″) long plastic tube? The answer may suprise you & your students!. If you place it firmly to your mouth (like a balloon), it will take many breaths to blow it up. But if you hold it out in front of your mouth and blow, air pressure in the stream you produce is reduced, entrapping surrounding air to join in, filling up the bag. You can blow it up with a single breath! This is especially effective after your students have counted many of their own breaths in attempts to fill up the bag!
