How to get bubblier bubblesIf you have ever wondered how bubble
blowers can blow such big ones that last for a long time floating in
the air, you will be interested to know how this science fair projects
sample which teaches you to make bigger and longer-lasting bubbles.
The trick here is to add sugar to the detergent solution. You can use
plain table sugar, corn syrup or glycerin.Mix 1 cup of detergent with
9 cups of water and 8 tbsp. of the syrup or glycerin or sugar gently
stirring it until it forms soap bubbles. To make sure that no alcohol
is left in the detergent (in case there was any), let the solution
stand overnight. By morning you should be ready to produce those big
and lasting bubbles on your bubble wand.A chemical explanation of why
this works can be found in the science fair projects instructionsCool
FlameIf you have ever heard of a type of fireworks called ice
fountains, you should know that they are based on a technology of
producing fire called cool flame. This type of flame gets as hot as
300 to 400 degrees C.This science fair projects sample involves
immersing paper into an alcohol solution until it is soaked. If a
match is then applied to the paper, the alcohol burns with a cool
flame which will not be enough to incinerate the paper. So you
actually have fire that doesn't burn here.Ice fountains, otherwise
known as 'green' fireworks, use this type of flame to set of its
pyrotechnics. The result is that this type of fire display produces
minimal residue and is cool enough to hold in your hand while it
burns.Gas bubbles in a fermenting solutionMost of us know that drinks
like wine and beer are made by fermenting sugar in juices and beer
malts. The action of yeast on the sugar is responsible for the
formation of alcohol and the release of CO2 gas into the
atmosphere.This science fair projects sample demonstrates the
production of CO2 gas during fermentation. Mainly you will need fruit
juice that has been mixed with some water and some wine yeast. After
the yeast has been added to the juice, following all the necessary
preparations, cap the jar with a balloon and hold the balloon fast
along the sides of the jar's mouth with some rubber bands. Use a pin
to punch small holes into the balloon.After about half a day, you
should see the balloon swelling up because of the gases that are
escaping from the solution.Useful science fair projectsThere are
science fair projects which are not only enlightening, but also
practical. For instance, plants which you find to be repellent to
insects could be planted around the house to minimize mosquitoes and
other pests. Science fair projects for creating electricity from
sunlight can be used eventually to power the light electrical
appliances in a house.The projects about wine fermentation are good
introductions to home wine-making, an industry that is picking up in
these hard times. Home-made wine is much cheaper than commercially
bought ones.
