1, bubble fountain
Pour some hydrogen peroxide into the container, and then add some detergent. Blowing gently into the container with a straw will produce a large number of bubbles and form a fountain effect.
2. Flame test
Pour some hydrogen peroxide into a small dish, then dip a cotton swab in some salt or sugar and put it on the dish. Light a cotton swab and put it on the hydrogen peroxide. Due to the existence of hydrogen peroxide, the flame will become brighter and more prosperous.
3. Floating eggs
Put a raw egg in a glass of water and observe that it will sink to the bottom of the cup. Then slowly pour the eggs into another cup and add enough hydrogen peroxide to soak them. It is observed that eggs will float on the surface of liquid because the density of hydrogen peroxide is higher than that of water.
4. Floating paper
Cut a piece of paper into small pieces and put enough hydrogen peroxide in the container to soak it. It is observed that paper will float on the surface of liquid because the density of hydrogen peroxide is higher than that of water.
5, reaction observation
Pour some hydrogen peroxide into the container, and then add a spoonful of yeast. It is observed that yeast can rapidly decompose hydrogen peroxide and produce a large number of bubbles and foams. .
6. Floating grapes
Put some grapes in a cup and soak them with enough hydrogen peroxide. It is observed that grapes will float on the surface of liquid because the density of hydrogen peroxide is higher than that of water. 7. Floating rose: Put a fresh rose in a cup and soak it with enough hydrogen peroxide. It is observed that roses will float on the surface of liquid because the density of hydrogen peroxide is higher than that of water.
Step 7 clean hard surfaces
Pour some hydrogen peroxide on a hard surface that needs cleaning, such as bathroom tiles or kitchen countertops. After scrubbing with a brush for a few minutes, you can see that stains and dirt are effectively removed.
8. Floating candles
Pour some hydrogen peroxide into a container and put a candle in it. It is observed that candles float on the surface of liquid because the density of hydrogen peroxide is higher than that of water.
9. Floating oranges
Put an orange in a cup and soak it with enough hydrogen peroxide. It is observed that oranges will float on the surface of liquid because the density of hydrogen peroxide is higher than that of water.
10, floating rubber duckling
When the rubber duckling is put into the hydrogen peroxide solution, the hydrogen peroxide begins to decompose and bubbles are produced. These bubbles will stick to the rubber duckling and make it float in the solution.
