Eggs stronger than bricks? | Live Experiments (Ep 3) | Head Squeeze

Science/Engineering Presenter Garry Lavin shows us that eggs shells aren't as brittle as some might think. In this video he lays bricks on them to show an egg shells sheer strength. He also uses his drawing skills to show why they are so strong. Live Experiments: Our resident daredevil science fiends will give the YouTube audience their big science treat each week with an experiment where you can find out how to make food dance, power a light bulb with household objects and create mega smoke rings! RECIPE IMPORTANT: You will need one sober adult with a sense of scientific wonder... What you need to get started is: 6 eggs (You only need 4 but I'd advise 6 as a precaution), 3 bricks, a bowl, masking tape, a marker, a tablespoon, a knife, scissors and some old sheets of newspaper 1. Place some old newspaper on your work surface to keep your home clean 2. Tape one strip of masking tape around the centre of the egg 3. Get a marker and draw around the centre of your strip of masking tape 4. Use you table spoon to hit one end of your egg to make an indent 5. Then use a blunt knife to pierce through the indent and drain your egg 6. Once the egg is drained carefully cut around the line on your masking tape (It has to be perfect or the egg shell will collapse under the strain of the bricks - so take your time.) 7. You can now remove the masking tape from your egg shell - repeat this process until you have eggs shells of equal size. 8. Create a rectangular shape with 4 egg shells that will be used to support your bricks. 9. Line up a brick so that the for corners will are evenly distributed on the egg shells 10. Place one brick at a time on top of the egg shells 11. Remember to stand well back after each brick is laid on in case the eggs collapse. 12. Stand back and leave for a 10 second interval before you place on your second brick 13. Stand back for another 10 second interval and then lay on your final brick 14. Slowly remove the bricks once you have completed this experiment" Check out this video on Earth Unplugged for why eggs are shaped that way:    • Видео      / headsqueezetv   http://www.youtube.com/subscription_c...
