Q: Make sure that the flask you choose is big enough to rest on top of an available beaker without falling inside. The flask of ice will allow the iodine gas to cool rapidly to a solid. Place the iodine in a beaker. Put the round bottom flask full of ice on top of the beaker. Heat the beaker on a hot plate to turn the iodine to a gas.  The whole process is extremely messy and the large amount of iodine vapor will stain everything. Do not do this indoors. Iodine gas is toxic, so this should be performed outside or inside a fume hood. The iodine will form a purple gas and solidify into a purple solid. When the iodine vapors come in contact with the cold round bottom flask, they will cool rapidly. This will cause the iodine to solidify and stick to the flask itself. Once this happens, you can simply scrape your iodine off of the flask to collect it. Heating and purifying the iodine is not necessary. It is an optional step to obtain a more pure version of the chemical.
A: Fill a round bottom flask with ice. Heat the iodine in a beaker. Scrape the iodine off of the round bottom flask.

Q: Many smokers believe that they will someday quit cold turkey they have to do is make a simple decision to do so. Nicotine is a powerfully addictive drug, so ending a smoking habit abruptly can result in uncomfortable withdrawal symptoms with both physical and psychological effects. Though much of the effects of vaping have yet to be researched, studies show that vaping allows users to gradually wean down their nicotine use over time. This reduces the addictive properties of smoking, while also reducing the carcinogenic effects of tobacco smoke inhalation. Many smokers have used vaping to successfully end their smoking habit for good.  Vaping involves no fire or combustion but a device which is used to vaporize the E-liquid for inhalation. E-liquid usually contains propylene glycol, flavorings and optional doses of nicotine.  E -cigarettes are also battery powered devices which use liquid to produce a vapor for inhalation. These offer smaller doses of nicotine to reduce the discomfort of withdrawal symptoms and gradually reduce the amount of nicotine in the bloodstream. Most nicotine replacement therapy products are available over the counter, with the exception of inhalers.
