If not, your feckless feline could have been having an electrifying adventure like Freddy the cat who spent 18 hours stuck at the top of a power line. He climbed up the 7m pole but then was too afraid to climb down. Instead he clung on to wires – just a paw away from a live cable! Electricity engineers, firefighters and the RSPCA were called in to rescue the petrified puss. >>> Back to top 2. Over 2U! – – Science experiments for you to try at home...Hot Air BalloonYou will need:

Special Safety adviceTake great care with the boiling water. What's happening?The hot water heats the cold air in the bottle. As the air gets warmer, each of the molecules of air is given more energy, and so they travel faster. As the molecules are travelling faster they each have a higher momentum, which means they hit each other - and the side of the container - harder. Without the bottle and balloon containing them, the air molecules would all start moving away from each other: the hot air would expand. Since the balloon is stretchy, the expanding gas contained in the bottle and the balloon forces the walls of the balloon out and then it starts to inflate. Alternatively, you can look at this situation as an increase in pressure. The pressure of the air in a container is measured by the force that the molecules exert when they hit the sides. If they all have a greater momentum they hit the sides harder and the pressure increases. This pressure increase pushes on the inside of the balloon, and you have a slowly inflating balloon man. This activity came from the Breaking News film on the Scicast site. Check it out – and whilst you’re there how about submitting one of your own? >>> Back to top 3.
