## Sucking an egg into a bottle – heat and pressure experiment

Sucking an egg into a bottle Here's an interesting experiment that we promise you'll be talking about at school the next day. Find a bottle with a long, narrow neck and set it on the table.  The opening should be just small enough to keep the egg from falling inside. Boil and peel a egg. Have Mom or Dad drop 3 lit matches into the bottle (if Dad does the 'dropping' then make sure the fire extinguisher is handy). Quickly place the egg over the mouth of the bottle. What happens? The lit matches heat the air inside the bottle. When air is heated it expands (and takes up more room). As the heated air expands, some of it escapes out the bottle. When the matches…

## Super hero egg shells

Super hero egg shells Ever wonder why igloos are dome shaped and not square? Ever been amazed at how a suspension bridge can hold the weight of hundreds of passing cars with little or no apparent support underneath it? This experiment demonstrates how arches are used in architecture not only for aesthetic appeal but for a very useful and needed Carefully break off the small end of four eggs and pour out the insides.  If you're worried about wasting perfectly good eggs uhhh, Reeko's heard they're good for your Wind a piece of cellophane tape around the center of each eggshell. Cut through the center of the tape to make four dome-shaped shells (discard the broken end of each shell). Lay the four domes on…

## Floating eggs in salt water experiment

Floating eggs in salt water Density is a measure of how much matter takes up a certain amount of space or volume. The more matter you can pack into a certain space, the denser it is. Although we often confused the two, density and weight are actually two different measurements. Weight is defined as the mass of an object times the force of gravity. In our world where we have gravity forcing things downward, a denser object will be heavier too. Clear as mud? Well, let’s do this experiment and at least make it as clear as, err… salt water. Since density is defined as how much matter takes up a certain amount of volume, we can take ordinary water, add salt to it, and…

## Magic balloon egg

Magical fun with eggs If you're the type of person who finds yourself shouting, "I want and I want it NOW" then this experiment might not be for you. It'll take 10 days to see the results of our experiment but when all is said and done, we'll have one of the weirdest eggs you've ever seen. Magicians have created eggs like the one we're about to make, for many years. As early as 1900, magicians created these "magic eggs" and used them as props in a variety of magic tricks. Imagine if you could remove the "hardness" from an egg shell giving you an egg that could be folded like a napkin or blown up like a balloon? The egg could be folded to…
