One less blow, and the balloon is underinflated one more, and a neck will form. Full inflation is defined as the point at which it becomes preferable for the neck of the balloon to take any additional air, rather than the round "bulb." This gives rise to a tear-drop shape. The right size for most games and decorations. This is a fully-inflated balloon-not underinflated, not overinflated. Crushing an underinflated balloon will displace air into the uninflated neck portion, and most of the time, the balloon can redistribute its stresses without popping. Not useless though: games that require sitting or stomping on balloons to pop are made more interesting by underinflated balloons. Note the round shape and long uninflated neck. These three pictures are all the same balloon: a 12" Unique. I'll refer to these levels of inflation as I continue. First of all, let me offer a quick visual inflation guide. So no matter your particular interest in balloons, perfect inflation is the most important tool available to you. Balloons that are not fully inflated aren't the right shape or the right color, and never have the shine that properly inflated balloons do (see Rubber Chemistry 101 for why). I don't know about you, but when I inflate balloons, I want to get the most for my dollar. What “yeast food” helps the yeast create the most gas? (try sugar, syrup, honey, etc.There are few things more disappointing than a party decorated with underinflated balloons. What water/room temperature helps the yeast create the most gas?Ĥ. Does the size of the container affect how much gas is created?ģ. Does room temperature affect how much gas is created by the yeast?Ģ. To make it a true experiment, you can try to answer these questions:ġ. ![]() (I’m sure you were wondering about that.) Anyway, when the bread gets baked in the oven, the yeast dies and leaves all those bubbles (holes) in the bread. Naturalist’s note – The yeast used in this experiment are the related species and strains of Saccharomyces cervisiae. Each bit of yeast makes tiny gas bubbles and that puts millions of bubbles (holes) in our bread before it gets baked. Believe it or not, yeast is actually living microorganisms! When bread is made, the yeast becomes spread out in flour. We all know that there are “holes” in bread, but how are they made? The answer sounds a little like the plot of a horror movie. The gas fills the bottle and then fills the balloon as more gas is created. If all goes well the balloon will begin to inflate! How does it work?Īs the yeast eats the sugar, it releases a gas called carbon dioxide. Let the bottle sit in a warm place for about 20 minutes Blow up the balloon a few times to stretch it out then place the neck of the balloon over the neck of the bottle.ĥ. Like people, yeast needs energy (food) to be active, so we will give it sugar. Add the sugar and swirl it around some more. (As the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.)ģ. Add all of the yeast packet and gently swirl the bottle a few seconds. ( When yeast is cold or dry the micro organisms are resting.)Ģ. Fill the bottle up with about one inch of warm water. A packet of yeast (available in the grocery store)Ī small, clean, clear, plastic soda bottle (16 oz.
