The Standard "Right-Side-Up" Version Using a pair of scissors, cut a strip of paper about 8" x 1. " Carefully use a match or lighter to light the strip of paper at one end and drop it into the large-mouthed bottle.
While the strip of paper is still burning in the bottle, set an egg on the mouth of the bottle. Watch carefully! Get the Egg Out of the Bottle! Want to do the experiment again? The "Eggsclusive" Upside-Down Twist Carefully push two or three small birthday candles into the narrower end of a hardboiled egg. Hmmm...
Carefully fill the balloon with water so the balloon is about the size of a tennis ball. In the traditional version of the Egg in the Bottle experiment, the burning piece of paper heats the molecules of air in the bottle and causes the molecules to move far away from each other. In the Upside-Down Twist, the science is the same as the traditional Egg in the Bottle trick, but the whole thing is just inverted.

A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light.
When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight. The white light from the sun is a mixture of all colours of the rainbow. This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. Tyndall Effect The first steps towards correctly explaining the colour of the sky were taken by John Tyndall in 1859. This is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering—after Lord Rayleigh, who studied it in more detail a few years later. Dust or Molecules? Tyndall and Rayleigh thought that the blue colour of the sky must be due to small particles of dust and droplets of water vapour in the atmosphere.
