Pharaoh's snakes I - sodium carbonate + sugar
Materials: porcelain bowl, skewers, pipette
Chemicals: ashes, ethanol, C 2 H 5 OH, sugar, sodium carbonate
Procedure: Pour into a bowl ashes of cigarettes (moisten with alcohol), we make a dent in the middle and pour it into a mixture consisting of 10 g of powdered sugar and 1 g of sodium carbonate part Re-moisten the mixture with alcohol.Thus prepared mixture is ignited skewers and pipette when minimum alcohol. The bowl will begin to climb Pharaoh snakes.
Ash serves in this case as a catalyst. Caution When adding ethanol, there is a risk of burns
Other possibilities mixture:
Pharaoh's snakes II - potassium dichromate, potassium nitrate and sugar
Tools: mortar, aluminum, asbestos net, trivet, burner, boat
Chemicals: Potassium dichromate, potassium nitrate, sugar
Procedure: Pour into mortar 2 g of potassium dichromate, potassium nitrate 1 g and 3 g sugar. All perfectly homogenous and spoon so that the mixture should generally yellow in color. as follows: the mixture wrap in aluminum foil. The end of the roller on one end closed and open end ignite burner. Attempting to perform asbestos net. When burning a roller Pharaoh had a long climbs. The nascent oxygen allows the conversion of sugar to caramel, which produces a mixture of carbon chromitým and chromate. The mixture has a greater volume than the initial pressure and the prepared mixture is formed in a closed space into bizarre shapes. The roller must be tightly sealed and packaged. It is advisable to roll retie with string or rubber band.
Pharaoh's snakes III - rhodanides mercuric
Tools: hour glass, tripod, asbestos net, burner
Chemicals: mercuric thiocyanate
Procedure: the watch glass pour about 0.5 g of mercuric thiocyanate and warm. Thermal decomposition will evolve from the original white powder yellow Pharaoh's snakes. Substance swells, changes color and moves.
Mercuric thiocyanate decays to form a mixture of mercuric sulphide, carbon mercuric and mercurous oxide.
Mercuric thiocyanate may be prepared by reacting solutions of mercuric nitrate (34.3 g in 100 ml water) with a solution of ammonium thiocyanate (7.6 g in 100 ml water). A white precipitate of mercuric thiocyanate by filtration and dry it between filter papers and dosušíme the open air.
Pharaoh's snakes IV - monohydrogenuhličitan sodium and sugar
Pharaoh flower by BoboAUG
Lay the book Straka - Magic experiments in chemistry (1997) (see FTP)
Unfortunately umačkaná mixture in a foil tube by burned very unevenly on and off, mix freely poured in a foil tube by had a similar problem, but lasted longer burn. That's why I got down to the last possible option and to freely mix the pile. Created something that does not resemble a snake too .. it's more like Pharaoh flower.
