Very good, the general reagents and experimental instruments have, but some do not, such as cotton and the like.
Very real to restore, can think of the chemical reaction which is generally there. The bright spot is the ability to adjust the reaction speed and air composition, just conscience.
Used as entertainment or can. But there is a question, test tube in the iron platform should not be able to adjust the angle? Tried many times do not work, resulting in the preparation of oxygen when the tube exploded.
