The reaction between ammonium thiocyanate and barium hydroxide octahydrate is endothermic. It absorbs heat from the surroundings. As a result, the temperature of this reaction will drop quickly. This causes the beaker used to freeze to the wooden board. In this video, the beaker was able to hold approximately 9kg.

Do you have badly burnt/dirty pots or pans? Don't scrub them! Clean them with drano (i.e. lye, sodium hydroxide, caustic soda NaOH). WARNING - be carefull as not to burn yourself as this chemical is extremelly caustic.
Chemiluminescence of luminol. Two solutions are combined, the first solution contains luminol and sodium hydroxide. The second solution is 0.03% Hydrogen peroxide and potassium ferricyanide.
The luminol and the hydrogen peroxide react to cause the chemiluminescence. The iron in potassium ferricyanide is a catalyst for the reaction.
This is also used by crime scene investigators. A solution of hydrogen peroxide and luminol is placed into a spray bottle. When the solution comes into contact with blood, the iron present in hemoglobin will catalyze the reaction and it will begin to glow.

Watch Chemistry Magic. Watch as the color changes from purple to green to orange as the permanganate ion is reduced.
For this test I combined a half teaspoon of oxyclean and half teaspoon of baking soda. The results are way better than I could have imagined.
Here is a small video describing how my cell is put together.

The traffic light reaction sees a solution change colour from green to red to amber. More at
Ice is added to a dry Pyrex bowl. When the Ice melts the water reacts with the calcium carbide (place on the bottom) to produce acetylene gas and calcium hydroxide. The acetylene gas then explodes into flames when a match is place on top. It will continue to burn even as the ice melts because it keeps producing acetylene until the calcium carbide runs out.Kent
All the alkali metals react with water to produce elementary hydrogen and the corresponding alkali hydroxides. The reactivity increases with increasing periodic number. The reactions2 Na + 2 H2O ----> 2 NaOH + H22 K + 2 H2O ----> 2 KOH + H2I got lucky with this sodium reaction, I have never had such a perfect explosion.
it's the reaction of barium hydroxide with ammonium chloride..
Since I finally got my amp meter, I figured I should put a video together to show the actual amperage the FlipCup Fuel Cell draws.
