How to get bubblier bubbles

If 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 instructions

Cool Flame

If you have ever heard of a type of fireworks called ice fountains, you should know that they are based on a technol ogy 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 solution

Most 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 ferment ation. 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 projects

There 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.

Question by Insomnia Victim: Will an enviromental science major help me get into med school? I'm planning to study medicine, my goal is to become an orthopedic surgeon. It's my passion. I will begin college on fall. I want to major in environmental science, because I've always loved ecology and environment (not as much as helping people and saving lives) but I find it more interested than just chemistry and stuff. Do you think that with an environmental science major I could still get into a med school? Or maybe I should just go with a biology or chemistry major? Best answer for Will an enviromental science major help me get into med school?:

Answer by Kayla
Tessie, you can get into medical school with a Spanish major. Regardless of major, you are required to take certain science courses. It is your grade in those they will be looking at - along with your MCAT scores. Make sure you've got experience as an EMT or scribe or something too if you want to be competetive.

Answer by 2ro
You can still get into med school with a degree in environmental science, but youre still going to have to complete your medical school prerequisites such as chemistry, organic chemistry, and calculus off to the side if they are not included in the environmental science degree plan
