This simple demonstration can be used for fun, such as on open days, or to provide an illustration of the effect of composition of a flammable gas and air mixture on its explosive properties. The experiment can also be linked to domestic gas explosions, along with this similar demonstration using methane to create an explosion inside a tin can.

Then, sprinkle the pepper on to the water, covering a much of the water surface as possible. The more pepper, the more fun. Physical reaction or change: a change in which the physical properties (state, size, shape) of a substance alters, but the chemical make up remains the same. Get ready for an explosion of colors with the Exploding Rainbow Easter Egg experiment! Students should definitely try this exciting and visually captivating activity.In this experiment, students observe as a large fizzy drink bottle, from which the base has been removed, is filled with hydrogen. The hydrogen is allowed to burn at a small jet in the stopper of the bottle. As the hydrogen–air mixture changes in composition, an explosive mixture is reached, which students can witness exploding with a load bang. Then add the baking soda, dish soap, and a little bit of food coloring or washable paint. Using washable paint instead of food coloring will help you avoid staining. understand, in terms of collision theory, the effect of a change in concentration, temperature, pressure and surface area on the rate of a chemical reaction Get a sheet of paper and draw two big arrow on it, one near the top, and one new the bottom. Make the arrow point in the same direction. Make sure emergency equipment such as eyewash stations, emergency showers, and fire extinguishers are readily accessible. Memorize where the fire alarms are and the number to call. Have an evacuation plan. Keep the SDS readily available to show emergency responders. Advance planning can save precious seconds and your life! References

Never perform potentially explosive experiments when alone in the lab. Inform your lab mates before starting the experiment. Static Electricity | Another classic demonstration that your kids will love! Just one material needs and loads of fun. Turn your very own head into a fireworks display! {figuratively speaking, of course}In this experiment, students observe what happens when cornflour is sprayed into the flame of a candle burning inside a large tin can with the lid on. The resulting small explosion caused by rapid combustion of the cornflour blows the lid off the tin. The explosive decomposition of energetic compounds can be triggered by heat, mechanical stress, light, catalysts (e.g., metals), or sparks. The sensitivity to each factor varies with the compound. Often, the stability of a compound decreases with increasing concentration, and the pure or dry compound is the most sensitive to decomposition. Scale of the experiment You’ll want to make sure that you can still read the temperature on the thermometer. It’s a great idea to poke a hole if possible through the covering so that the thermometer can fit through it, and you can easily read the temperature. Kids will be amazed watching this stunning rainbow science experiment. This experiment uses Hydrogen peroxide, food coloring, liquid dish soap, dry active yeast and lukewarm water. When combined the liquid turns into an exploding rainbow. Make sure kids are well supervised when doing this experiment but the foam is safe to play with, just not the liquid. The other super cool thing about this exploding experiment is that it is exothermic, meaning it gives off heat! Visit Science Kiddo to find out more. 6. Mentos Geysers

Experiment with putting different objects into the paper cup and see how it affects the parachute’s effectiveness. Does the parachute flight time increase or decrease? If your child is a fan of the Horrible Science books, they will love this Horrible Science Explosive Experiments kit. Have you heard of the elephant toothpaste experiment yet? It’s a blast! You will need an adult for this experiment. Kids of all ages will love learning about catalysts and exothermic reactions in this simple fun science activity.

Cut the bottom off the drinks bottle and replace the cap with a bung carrying a short length of glass tubing to which is attached a short length of rubber tubing and a clip – see the diagram below. The glass tube must not protrude into the bottle beyond the bottom of the bung. Another spin on a classic volcano science experiment is an ice volcano. These are perfect for bringing outside on a hot summer day! Miss 5 has been wanting to make an exploding volcano for a while now. The school holidays are coming up so that wish may just come true! Once she and her sister see this list they will be wanting to do them all. Which will you try first? You might even have most of the needed ingredients at home! 7 Kids Exploding Experiments 1.Erupting Volcano
