B Buzz + Light our own racing games, concetration, balance and speed. Don't let the buzzer go off
C Carbon Dioxide produced by mixing half bottle of vinegar with some Bicarbonate of Soda inside a balloon.
Balloons blow up and some disintegrate producing a shower of vinegar! Not intentional..
C Cartesian Diver, water + salt + ketchup satchet + 1 litre bottle of water
C Codses & spying the Secret Cypher Wheel, hidden code written in lemon juice, then heated to reveal.
C Colour changing milk. Unusual things happen when mixing milk with food colouring & liquid soap
C Compass Points - using and NESW, being conscious when outside of directions. Large card game
C Compass Points At sea - Port, Red, Left (all short words) - Starboard, Green, Right (all long words)
C Compass Points, how to find 'South' with just an analogue watch.
D Density in liquids, varying, honey, veg oil, wash up liquid, vinegar, food colouring & liquid soap
D Density making a lava lamp with different density lquids and some alka saltzer tablets to make it fizz
D Dry Ice - Solid Carbon Dioxide, see results with warm washing up liquid. -110F -78 C
D Displacement of water by boats/ships at sea. How do they float? Made small boats of plasticine that floated & some sunk!
E Elements - collecting samples, labelling.
E Elephant's Toothpaste, see result of mxing some chemicals
E 'Energy Stick' from Steve Spangler USA, human circuit, low voltage, electrons, atoms, circuit, resistance, insulation.
F Fluorescent tube - how to light without mains electricity - non touching plasma globe
F Flourescent tube - how to light without mains electricity - using static from balloon
G Glow water, how to make - soak-stir ink from several highlight pens. Result reacts to UV light
H Human Battery using alum foil, copper tube and multimeter to measure millivolts.
H Human circuit with electrons flowing around with group holding hands and using the electron buzzer
K Kitchen Volcano, vinigar, baking soda + food col + flour, a mess but great fun.
L Lie Decector, very basic example uswing alum foil, copper tube and multimeter to read 'human circuit',
higher voltage when supposedly telling a fib!
L Light Refraction - a glass bowl disappears...index of pyrex and veg oil similar, glass bowl within glass bowl.
L Light Ultra Violet, petroleum jelly - reactive.
L Light Fibre Optic - 1 litre bottle, small amount of water through hole, torch showing how light can be bent
M Magnets - lots of them including neodymium and magnetic iron filings. North/South Poles attract. Like poles repel
M Magnesium Ribbon - burns at high temperature approx 700C
M Measuring lquids using 05 ML and 0-20 ml syringes
M Medical, full size skeleton ' Freddie' quizzes about bones and organs.
M Microscopes x 8 + USB, monocular, binocular, checking out different slides
M Mobius Strip - a surface with only one side.
O Optical Illusion. 'Seeing A Sausage' right in front of our eyes
O Optical Illusion Checking out our 3 show boards of 3D Stereograms
P Periodic Table, match pictures with elements. Elements song.
P Plasma Globes various various experiments
