Purpose: Removal of the stopper from an "Aladdin's Lamp" (any opaque bottle or container) results in the delayed evolution of a large cloud of water vapor some what like the mystical "jinni".


These are all that you can do. Some of these look fun, I might do it by myself... Here's a website that would give you the EXACT same experiments. There is also a list that tells you what you need and what to do.

Answer 2

Chemical volcano: though it is old but it is fast and good also it is working. Also another is christmas tree in water. For further details write to me. details THEORY first i wish to let you go with the theory of chemical volcano, likewise real volcano it emits smoke, little fire, and a small bust of dust, for this purpose we use ammonium dichromate [(NH4)2Cr2O7], The eruption of an ammonium dichromate [(NH4)2Cr2O7] volcano is a classic chemistry demonstration on making it to burn. The ammonium dichromate glows and emits sparks (equivalent to light and spark of real volcano) as it decomposes and produces copious amounts of green chromium (III) oxide ash (dust and lava, magna of real volcano). This demonstration is simple to prepare and perform. The decomposition of ammonium dichromate commences at 180°C, becoming self-sustaining at ~225°C. The oxidant (Cr6+) and the reductant (N3-) are present in the same molecule. menakshi remember this thing for your board exam that ammon. Diachromate is a oxido-reduction process of self oxido-reduction reaction. (NH4)2Cr2O7 --> Cr2O3 + 4 H2O + N2 The procedure works well in both a lighted or darkened room. MATERIAL REQUIRED 100 grams of ammonium dichromate sand tray or ceramic tile, for use in ventilation hood OR 5-liter round bottom flask and porcelain filtering funnel putti or the clay readily available in market which is used to fix window glasses. gas burner (e.g., Bunsen) OR butane lighter or match, for use with flammable liquid (e.g., ethanol, acetone) PROCEDURE If you are using a hood: Make a pile (volcanic cone) or ammonium dichromate on a tile or tray of sand using the putti or you can also replace putti with simple black soil OR u can use any material which can cast you the shape of a volcano like.. Use a gas burner to heat the tip of the pile until the reaction begins or dampen the tip of the cone with a flammable liquid and light it with a lighter or match. If you are not using a ventilation hood: Pour the ammonium dichromate into a large flask. 1. Cap the flask with a filtration funnel, which will prevent the majority of the chromium (III) oxide from escaping. 2. Apply heat to the bottom of the flask until the reaction begins. 3. and till the volcano erupt and let to go itself. notes Chromium III and chromium VI, as well at its compounds, including ammonium dichromate, are known carcinogens. Chromium will irritate the mucous membranes. Therefore, take care to perform this demonstration in a well-ventilated area (preferably a ventilation hood) and avoid skin contact or inhalation of the materials. Wear gloves and safety goggles when handling ammonium dichromate.

Answer 4

vinegar and baking soda

HC2H3O2 (acetic acid) + HCO3- (bicarbonate ion) ----> H
H2CO3 (carbonic acid) + C2H3O2- (acetate ion)
H2CO3 -----> H2O + CO2
The foaming is the liberation of CO2 gas when carbonic acid dissociates.

put some popcorn seeds in to show the CO2

Answer 5

You can do something related to greenhouse gases and global warming.

Answer 6

A foaming volcano..
