Ten Awesome Lego Science Experiments - Make Science Fun 30 Seconds of pure Lego Science Bliss. Ten Science experiments in 30 seconds.

1. A measuring cylinder contains water with some universal indicator. The water has been made basic using a small chunk of washing soda which is sitting at the bottom of the cylinder. A small lump of dry ice (solid carbon dioxide) has been dropped in. As the dry ice sublimates, the carbon dioxide reacts with the water causing it to go acidic (carboxylic acid). This causes the universal indicator to go green, yellow, orange and red.

2. A drill is used to make Legoman orbit a circular path. This is an example of circular motion. The tension in the wire supplies the necessary centripetal (centre seeking) force.

3. A small glass contains some water, universal indicator and a chunk of dry ice (solid carbon dioxide). As the dry ice sublimates it produces cold carbon dioxide. This causes water in the air to condense, producing a white cloud. Some liquid soap mixture is wiped over the rim of the glass, allowing the bubble to form.

4. A small chunk of dry ice is put in a small rocket with some water. The pressure builds up as the dry ice sublimates (turn to a gas). Eventually the pressure pushes the water and gas downwards. The water and the gas then in turn push the rocket upwards (Newtons third law)

5. Timelapse over 30 minutes. A chunk of dryice is put into some Oobleck. This causes the Oobleck to freeze. You can see ice crystals from the air forming on the Oobleck. Eventually the dry ice has finished sublimating and the air warms the Oobleck, causing it to melt and turn back to its normal form.

6. Magnetic Stirrer. The beaker containing water with some universal indicator and a little acid, and a ‘Flea’ (magnetic stirrer) is sitting on a magnetic stirring machine. As the flea spins, it creates a vortex, which the legoman is caught up in. Drops of sodium hydroxide are being added in the top right hand corner, causing the universal indicator to go purple.

7. Flame vortex. A flame is turned into a tornado using a spinning flyscreen mesh. The coloured flames are due to different coloured salts.

8. Burning pencil! The conducting graphite lead in the pencil is connected to a 12 volt battery source. The resulting current produces heat which causes the pencil to burn up.

9. Conical flask explosion. Some blue water is being boiled in a stoppered conical flask. As the pressure builds up, it eventually blows the stopper off causing legoman to go flying. I’m not sure what causes the water to burst out though!
