How does the length of time that a soda bottle is open affect its fizziness?
Because all soda is carbonated the longer it is open the less "frizzy" it will be.
As the carbonated soda and flavored syrup are exposed to air they release carbon dioxide gas which release and do not recombine with the liquid.
Depending on the level of carbonation it can take anywhere from a few minutes to a few hours for all of the the co2 to escape.
Don't try this on beer or champagne unless you are conducting a well funded scientific experiment.
Waste soda not happiness.
Turn an opened plastic bottle of washing-up liquid upside down. The liquid will drip out of the bottle as it is only under the force of gravity, and held back by the suction of the bottle. Press forcefully on the plastic bottle, and the liquid will squirt out of the bottle - simple because you have applied a force (pressure) on the bottle. A garden hose-pipe shows the same. With the water tap slightly open…
There's a bleeding screw in the caliper, i believe it 8mm. Unscrew it a little to open it. Attach a length of house to it. Take a 20 oz bottle and fill it a quarter if the way with brake fluid. Take the other end of the hose and stick it in the bottle. Open the brake fluid reservoir. Then turn the key to the on position and pump the breaks to the desired stiffness.
How much dry ice would you require in a bottle to make the sound of gas escaping when you open the bottle?
If you have the right milk, get a livestock bottle (large version of baby bottle) and fill it with the (warmed) milk. You might have to rub the foals lips with the nipple a bit to get it to open up, but eventually, it will open its mouth and begin drinking. (let the foal suck on the bottle, and do not force the foal to drink.) Ask a vet if your foal is not responding…
