Spontaneously combustible mixture
Tools: alcohol burner, bar, porcelain bowl, beaker, boat
Reagents: potassium permanganate, concentrated sulfuric acid
Procedure: about a quarter of small boats finely minced potassium permanganate pour a small amount of sulfuric acid to form a thick slurry. Apply slurry particle sticks to wick alcohol lamp, which ignited.
Tools: mortar, asbestos net, pipette
Chemicals: zinc powder, ammonium nitrate, ammonium chloride
Procedure: 4 g of zinc powder gently mix well with desiccated and crushed 4 g of ammonium nitrate and 1 g of ammonium chloride. Drops of water set in motion a reaction - beware of violent ignition of the mixture (working on a non-combustible surface.)
It is a catalyzed reaction in which ammonium nitrate decomposes, releasing the heat and zinc powder burns.
Reagents should be dried at 120 ° C and the mixture was thoroughly homogenized. Larger quantities of water the reaction stops.
Tools: mortar, skewers, pipette
Reagents: potassium chlorate, sugar, concentrated sulfuric acid
Procedure: a mixture of 1 g of powdered potassium chlorate, and 1 g of sugar sharp flares flame, I add to it with concentrated sulfuric acid. We provide in a mortar. Chlorate is located on chloride and releases oxygen, which reacts with carbon in sugar.
Tools: mortar, asbestos net, pipette, beaker
Chemicals: iodine, aluminum powder
Procedure: In a mortar spoon 2 g of aluminum powder previously dried at 120 ° C with 3 g of iodine. To the mixture to a net asbestos Put a few drops of water. The mixture is a moment ignite and burn rapidly.
Resulting heat of reaction of iodine in the form of vapor escapes into the atmosphere.
Friction iodine with aluminum is made in a completely dry mortar - přikapáváme only 2-3 drops of water! Powdered aluminum can replace stříbřenky. This is catalysed reaction - the catalyst is H 2 O. Instead of aluminum can also be use magnesium or zinc
Reagents: potassium permanganate glycerine
Procedure: Sprinkle a pinch of minced permanganate on the mat and add a few drops of glycerin
Probably the most famous and also the easiest to blend. After addition of glycerol occurs induction time 20-50 seconds (usually around 30 seconds).The mixture will burn for the development of large quantities of smoke. Better effect than the actual mixing substances Potassium wrap in toilet paper and create a bullet diameter of 3-8 mm. On a non-flammable surface (several layers of aluminum foil ...) Put a few drops of glycerin and formed ball with permanganate to put it ... Very imponujícího effect can be achieved by combining the permanganate gun cotton or blends FLASH No.9
Chemicals: hydrogen peroxide tablets (solid peroxide), sodium dithionite (in bleach rainbow)
Procedure: Lay a piece of foil 2 tablets of solid hydrogen peroxide and sprinkle them roughly double its volume amounts of sodium dithionite. Wrap 3 layers of aluminum foil into a tightly umačkáme into a spherical shape.
The mixture must be tightly in foil umačkat. Stronger impact on the ground, the mixture ignites and starts to reek densely white. In a globe can also drill 3 holes in the area where the peroxide and throw it into the water.After a while, the mixture ignites and starts to reek.
