Making a cloud with this palm-sized pump is easy. Remove the top and put a few drops of water inside the bottle. Add pressure using the pump, lift off the top and the cloud forms instantly inside the bottle! A Liquid Crystal thermometer strip records temperature changes during the experiment. What i...

A large affordable neon tube of length 300mm which, when connected to the Electrostatic High Voltage Genecon will be lit continuously and bright.Watch the video!

This amazing electromagnet is like an electric version of the Magdeburg Hemisphere but the resistance to pulling it apart is from the magnetic field generated by 1.5V batteries! Complete with a large easy to hold handle and safety catch to stop excessive backward body motion, students can discover t...

Deluxe class set of 20 high quality 40mm diameter compasses in a handy storage tray with a calibration strip that re-magnetises compasses into the correct orientation. In the tray, all compasses can be checked at a glance for correct North orientation. Each compass has a red triangle on the bottom f...

Spare Compasses (for 42CSST but can be used on their own), Set/10, 40mm diameter, with red triangle on the bottom face to assist students aligning it to North.

Easily viewed Compasses, Set/10, 40mm diameter. The transparent body allows viewing from almost any angle. Removable lid allows repositioning of the magnetic needle if it is accidentally displaced from the pivot.

Observation of three-dimensional magnetic field lines are stunningly brought to life in slow motion in this quality model as they slowly form around the alnico magnet in the center of the Silicon oil sealed chamber. The magnetic lines of force appear clean and well defined. This is the finest 3D mag...

provide a more tidy alternative to iron filings in making magnetic field observations by generating finely curved lines. The chips are made of 0.3 mm diameter zinc wire plated with iron and are about 2mm length. Class set of 300g total (x6 vials of 50g each).

Multi-coloured plastic-coated iron chips are not only easy to handle and clean up, but also heaps of fun! This alternative to iron filings puts some colour and excitement into the exploration of 3-dimensional magnetic fields. By connecting magnets in a variety of shapes, students can see dynamic cha...

This new has a combined voltmeter and ammeter which allows measurement and display of the electric power passing through it per hour. Suitable experiments are comparison of energy consumption of lamps connected to hand-held DC generators, or, comparison between (theoretical) potential energy and act...

Optical fibres are made of quartz or plastic with good transmission. Light incident on one end of the transparent fibre is reflected internally and transmitted to the other end. The high quality optical fibre in this set is made of transparent acrylic resin mixed with fine aluminium powder which all...

Good old-fashioned multi-coloured paper balloons! You can of course inflate them by blowing into the air hole, but it’s much more fun to inflate a withered balloon by bouncing it from hand to hand and watching it inflate mysteriously! How does this happen? Pack of 10.
