diapers are good insulators because they hold in the cold and and heat but is a bad conductor
Yes they are.
The rails are good conductors The wooden ties they rest on are insulators

A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.

It's insulators
Insulate the thermos with a very low heat-conducting material. Low density objects such as ceramic or foam are typically good insulators.
Heat, cold, pollution
the answer is a Thermos because it is made with insulators.
Thermos jugs are just very good insulators. Just like your house, they're designed to keep one or the other of extreme temperatures away from the inside of the jug ...and vice versa. FriPilot
I would guess that a vacuum thermos would be the best device to insulate a consumable liquid. The area of vacuum prevents heat loss or gain through conduction, and convection. I don't know how well it does to prevent radiation. I would think that prevention heat loss or gain through radiation would depend on what the material was made of. Also, if you keep the cap on the thermos as much as possible, it helps prevent heat loss or gain. Try to find the episode of Good Eats where Alton Brown talks about making sauces. I think I is hollandaise sauce that he talks about putting in a thermos and goes on to discuss how thermoses work.
Can be, if the vacuum is good. In glass thermos if the glass is not broken it is okay. In steel thermos if the vacuum has not been lost it will be. You can test a steel thermos by simply filling it with boiling water, if the outside of the thermos becomes hot the vacuum has been lost and one will need a new thermos.
Plastics are a good electrical insulators because they are insulators. Electricity could not pass through them unlike copper. Another good example of insulators is rubber.
Blankets are defined to be insulators.
The best thermal insulator is vacuum as in the gap of the thermos bottle. Another god thermal insulators is air (as in closed cell polyurethane foam or double glaze windows, or any gas in closed environment.
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
