Sam Brennan ran through the streets of San Francisco with a bottle of gold dust in 1848 to announce the discovery of gold at Sutter's Mill, sparking the California Gold Rush. He sought to capitalize on the excitement and attract miners and fortune-seekers to the area. His dramatic display was a clever marketing tactic that highlighted the wealth potential, ultimately transforming San Francisco into a booming city.
Sam Brennan ran through the streets of SF because he wanted to create excitement and sell his tools.

Small bottle.
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.
Convection in a hot water bottle is the transfer of heat through the movement of the water inside the bottle as it heats up. Conduction is the transfer of heat through direct contact between the hot water in the bottle and the material of the bottle itself. Together, convection and conduction work to warm up the contents of the hot water bottle.
Yes, a water bottle is typically translucent, meaning that light can pass through it but objects cannot be seen clearly through it. This allows you to see the level of water in the bottle and monitor how much is left.
u can use a tube and then pump it through with bottle (maybe a ketchup bottle) and run it through and you have a fountain!!
Water is filled into a bottle by pouring it in through the opening at the top of the bottle. The water flows into the bottle due to gravity, filling the empty space inside the bottle until it reaches the desired level.
Sam Brannan owned a general store during the time of the early gold rush. When he noticed that men were paying for items with gold, he bought out every mining tool in the region, filled a bottle with the gold shavings and announced down the streets that the Gold Rush was real and not just a tale. He bought supplies for a couple cents and was selling it for about $15.00. (which is equivalent to hundreds of dollars in today's value).

The most heat loss in a thermos bottle occurs through conduction, convection, and radiation. It mainly happens at the opening of the thermos bottle where there is direct contact with the surrounding environment, as well as through the materials used in the construction of the bottle that are not efficient insulators.
The green bottle appears green because it absorbs all colors of light except green, which it reflects back to our eyes. This selective reflection is what gives the bottle its green color when white light passes through it.
