They will die,you haft to put holes in the jar
If you put an inflated balloon in a jar and then remove the air from the jar the balloon will expand. Perhaps to the point of bursting, or to the point where it coats the entire inner surface of the jar.
Do not do it, it will explode!
Nothing special
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn out.
Pad the inside with lead wool and capture the demon in a jar put the jar in the washing machine and wait.
When you put a sealed glass jar full of air in the freezer, the temperature inside the jar decreases. According to the ideal gas law, as the temperature drops, the gas molecules inside the jar lose energy and move less vigorously, resulting in a decrease in gas pressure. Therefore, the gas pressure in the jar will decrease as the temperature lowers.
Sand is inside the 'Jar Of Dirt'.
because all the smoke that is being let off by the flame is trapped inside the jar causing it to go misty which will eventually turn into water vapour/ condensation. hope this helps :)
Condensation forms on the outside of the jar when you put ice cubes inside, due to the cold temperature of the ice cubes causing the surrounding air to cool and reach its saturation point. This results in moisture in the air condensing on the colder surface of the jar.
I'm sure you could put all of the gel in a jar or cup, put the roach inside and drown it.
A candle goes out when a jar is put over it because the jar restricts the flow of oxygen to the flame. A flame needs oxygen to burn, and when the oxygen supply is limited inside the jar, the flame will eventually suffocate and extinguish.
They last longer.
