This 15 litre kit is supplied in a plastic bag with handle. •Ideal for science departments •Contents absorb up to 15 litres of aggressive liquids Contents include; •10 x premier pads 500 mm x 400 mm •1 x premier 1.2 metre sock •1 x waste bag and tie

These chemical absorbents are designed and manufactured to deal with all chemical spillages, including most common acids, alkalis and solvents. They should be used where any aggressive chemicals are spilt and benefit from fast action, high absorbency, coloured for visual recognition, are simple to use and are heat bonded to prevent de-lamination during use. Non toxic and non reactive they reduce clean-up costs and time. Once contaminated, these absorbents must, of course, be treated with the same hazard caution as the chemical they contain and should be neutralised/disposed of accordingly. Box Weight: 3.8 kg. Sorbency: 0.55 litres per pad. Pad Dimensions (L x W): 400 x 500 mm. Supplied in pack of 100.

This fun resource can be used to demonstrate open and closed circuits as well as bringing some WOW to your science lessons. Completely safe to use, simply touch both the contacts on each end of the stick to form a complete circuit. When a circuit is formed the Circuit Maker/Breaker will emit a loud beep and the lights on the front will glow up. As soon as one of the contacts isn't touched, the circuit will be broken and the Circuit Maker/Breaker will stop working. Bring some WOW to your lesson by adding more and more people to the circuit! Get the children to form a circle linking hands so that the circuit maker breaker will light up and beep, but when the link is broken then the stick stops working. How many children can you get to complete your circuit? Add a further challenge by allowing the children to find objects to put in the link that will break or continue the circuit for the stick to work! Or use the Circuit Maker/Breaker as a tester of insulators or conductors by covering the ends of the stick with different materials and testing whether circuit can still be created. Based on teacher feedback, we have specifically designed the Circuit Maker/Breaker to be large in size so that it can be seen by all of the class. Measuring 15 x 5 cm in size and made from durable ABS plastic the Circuit Maker/Breaker is powered by 2 x AAA batteries with battery life of approx year in standby.

This toy has a serious scientific purpose because it provides a stunning demonstration of vortex formation and transmission. When the toy is 'fired' doughnut shaped ring of air (the vortex) is generated and moves outwards at high speed. It has sufficient energy to create a noticeable impact at some distance hence the toy interest. Ideal as a design project to attempt to recreate the same effect using cardboard boxes, etc.

A 5 mm dia. x 12 mm (when closed) spring made from shape memory alloy (NiTi). At room temperature this spring is soft enough to pull out to approximately 50 mm by applying a small force. When heated to 70°C by passing an electric current through it, the spring contracts to its original length with useful pulling force (equivalent to lifting 0.5 kg weight).

This remarkable alloy melts at just 61°C but, unlike the most familiar low melting point alloys, does not contain lead or cadmium. It is a relatively hard and extremely tough alloy that has a wide variety of scientific and manufacturing applications. It is used for example to fill small tubes for bending without crushing, casting for models and jewellery, and for making precision moulds. Although relatively expensive because it contains the rare element indium, Field's metal makes a fantastic demonstration of how several constituents, each with much higher melting point, can be combined to produce fusible alloy. Note: indium has risen in price recently because of its use in LCD TV screens. It 'wets' and adheres to many surfaces hence the propensity of Field's metal to adhere to plastics. Approx. 10 g.
