Genie In A Bottle Exothermic Reaction Experiment

The Genie in a Bottle experiment is an exothermic reaction. This means it releases heat. The soda bottle will get hot and shrink slightly. Oxygen is stored in liquid form in Hydrogen Peroxide. When we add the Manganese Dioxide (catalyst) it decomposes the Hydrogen Peroxide and oxygen is formed. The oxygen is rapidly released and steam vapor comes spewing out the top.

Make A Batch Of Bubbles That Dont Pop - They Bounce. Yeah Thats Right They Bounce!:

Make Bouncing Bubbles

The science of bouncing glycerin bubbles is fun. We all know bubbles normally pop when they are touched or come into contact with something. The walls of bubbles are tiny, a few millions of an inch thick at best. Normal bubbles pop when they come into contact with dirt or oil (common on hands, clothes and surfaces). Glycerin gives our bouncing bubbles their added strength. It's important the cotton gloves are clean when bouncing bubbles. If they have dirt or oil particles on them the bubbles will pop.

Blow Up An 8 Foot Long Bag In One Single Breath! Bernoulli bag aka Wind Bag Experiment Video

Bernoulli bag aka Wind Bag Experiment Video

This experiment is explained by the Bernoulli effect. The faster a fluid moves the lower the pressure it creates.Ask a volunteer to come forward to test his lung capacity against the champ "iron lung" science guy. The volunteer is asked to blow up the 8 foot long Bernoulli wind bag. After 20 or more blows his air is trapped and squeezed to the bottom to measure its volume. After the air is released, the science guy brings the bag to his mouth and fills it up with one single large breath. Amazing!

Hurricane Tornado in a Bottle Video

Hurricanes form out in the ocean when powerful storms meet up together and start swirling around generating vortexes. Vortexes are also formed in Tornado's, Whirlpools, and Dust Devils. In the experiment below you can make a Hurricane / Tornado in a bottle!

Singing Wine Glass Experiment And Video

So you want to be the hit of the party. Here is a classic that is guaranteed to please the crowd. All you need is a wine glass and some water. In this demonstration we will make a wine glass sing. Lets do the Singing Wine Glass Experiment!

Poke It Experiment And Video!

Amaze your friends, family and schoolmates by poking pencils through a ziplock bag filled with water. Imagine the shock when nothing leaks out. Learn about the sealing properties of polymers. Lets do the Poke It Experiment.

Whoosh Bottle Experiment And Video

The bottle begins full of air and oxygen. After we put the Methanol in the bottle it becomes volatile and evaporates rapidly. The liquid Methanol becomesMethanol vapor as we swirl it around the bottle. As it evaporates, a mix of air / oxygen and methanol is left inside the bottle. By adding a flame in the form of a

match, we are adding heat energy. This causes a combustible chemical reaction to occur between the oxygen and another Methanol vapor). The result is an exothermic reaction (a reaction in which heat is released). When you hear the sound of the "Whoosh" most of the oxygen has been used up and a jet of flame shoots up from the bottle neck . After which you may see a flame dance around inside the bottle and pulse for a few seconds. This happens due to left over methanol remaining in the bottle. However most the oxygen has been used up, so fresh oxygen is sucked down into the bottle from outside which re-ignites the methanol vapor again. This repeats until the vapor is gone. After the experiment you will notice the bottle has liquid in the bottom. This is carbon dioxide and water which is produced as a by-product of the reaction.

Water Suspension Experiment And Video

A fun and simple science experiment using a jar or wine glass, water, and a laminated card. Without a doubt it's guaranteed to make your audience go crazy with anticipation and astonishment! We will explore the properties of air pressure while entertaining the crowd. So lets try the Water Suspension Experiment.

Fire From Batteries and Steel Wool Experiment And Video

In this experiment we will make fire from batteries and steel wool. We will demonstrate how to use electricity to make heat and sparks. Then harness the sparks to create a fire. The project is easy and definitely fun to see. A regular 9 volt battery and extra fine steel wool are all we need for this experiment. We will also learn about fire safety and the "Fire Triangle".

Electrostatic Box

In this super cool science experiment we will explore the principles of static electricity, electrostatic charges, and induction. We will learn about electron transfer, repulsion of like charges and how opposite charges attract. We will witness graphite balls do amazing things as they jumps, dance, and stick.

Dust Off Cloud In A Bowl

In this experiment we will make a cloud in a bowl. Clouds form when water vapor cools down. Warm moist air in the atmosphere rises and the pressure reduces as it goes higher. As pressure reduces it gets colder. Eventually the water vapor cools enough to form clouds. We will use dust off compressed air and warm water to make condensation.

Elephants Toothpaste

In this experiment we will make a oozing foamy batch of elephants toothpaste. We will use 30% Hydrogen Peroxide and catalyst of Sodium Iodide to create the eruption for the Elephants toothpaste. In the process we will instantly release oxygen, water, and heat in an exothermic reaction that decomposes the hydrogen peroxide.

Polymer Hydrogel Oil Spill Experiment

Lets have some good old fashioned science fun and do an experiment to find out which materials best clean up an oil spill. We will use a super absorbent polymer called a hydrogel (also known as water gel or slush powder) to conduct our experiment. The polymer is the same stuff used in baby diapers. We will turn the oil into a solid then scoop it out! In the process we will learn about how oil spills effect the environment.

Make A Cloud In A Water Bottle

In this experiment we will make a cloud in a water bottle using a little rubbing alcohol. Clouds form when water vapor cools down. Warm moist air in the atmosphere rises and the pressure reduces as it goes higher. As pressure reduces it gets colder. Eventually the water vapor cools enough to form clouds.
