If the bottle is left in a place where the sun can shine through it, the bottle can magnify the heat from the sun and start a fire.
Leaving a glass bottle in a forest can harm the environment and wildlife. Glass does not decompose easily and can pose a physical danger to animals and humans. It's best to properly dispose of glass in designated recycling bins or facilities.
The temperature contrasts would cause differential expansion of the bottle which, being brittle, would cause the glass to crack.
if your strong enough and dumb enough yeah
Candles cause fire
it cant physically catch fire but it can cause an explosion.
leaving a glass bottle in the sun or smoking a cigarette
Grease the top of the bottle!
It is not advisable to heat up a glass bottle in a bottle warmer, as the high temperatures can cause the glass to break or shatter due to thermal shock. Most bottle warmers are designed for plastic or stainless steel bottles. If you need to warm a glass bottle, consider using a warm water bath instead, ensuring that the temperature is controlled and gradual. Always check the manufacturer's guidelines for safe heating methods.
To cut the bottom off a glass bottle effectively, you can use a glass cutter to score a line around the bottle where you want to cut it. Then, carefully heat the scored line with a candle or a heat source. After heating, quickly cool the bottle with cold water. The thermal shock will cause the bottle to break cleanly along the scored line.
One way to cut wine bottles without a glass cutter is by using a string soaked in a flammable liquid, such as acetone, tied around the bottle. After lighting the string on fire and letting it burn for a few seconds, quickly submerge the bottle in cold water. The sudden change in temperature will cause the bottle to break along the scored line created by the burning string.
The grass would presumably catch on fire, however, if the bottle was sealed, the fire would eventually burn out due to the lack of oxygen required to continue combustion.
The milk bottle would crack because the hot water would cause the glass particles to vibrate and move apart, this will make the glass expand from the heat and the glass will then shatter.
