Question for my science hw? It's about the insulation of heat.?

I'm in grade 7We are going to do an experiment tomorrowSo it's gonna be like this; there is going to be a test tube and inside, boiling water with a temperature in itAnd we have to bring a material that will keep it hot for as long as it canEgsocks to wrap around, or tape (i dont even know if it'll work)Such thingsI dont want it to be expensiveStuff that i can find in my houseI also read on another question that mirrors work as wellCan someone give me examples and if the mirror thing will work or not.

Answer:

forget mirrors Styrofoam and aluminum foil are bestFirst wrap it in foil, then surround it with styrofoamBroken up coffee cups are fineYou can use Duct tape to hold it in placeThen perhaps another layer of foilBut of equal or more importance is evaporationas soon it stops boiling, which will be as soon as you take it off the heat, get the top plugged up to prevent evaporationBut not tightly, you need to allow a little space for vapor to escapePerhaps a loose cork or a fairly tight one with a notch cut in the sideVery important is speedYou need to get the test tube capped and insulated as quickly as possiblePerhaps you can setup ahead of timeGet the cork setUse a piece of broom handle or another test tube to get all the insulation shaped and in placeThen just pop the one with the boiling water in there, put the cork on topUse insulated glovesPracticehave fun.
Back in my day we used this thing we used to call creativityWe'd get ideas and follow through on themSome worked and some didn'tThat's how we learned.
A bowl is gonna hit way better bro and i still smoke out of a bottle but bowls are just better and everytime you take a hit you can look inside from the whole you put your mouth on and you could see the smoke
Never heard of people smoking it outa plasticGet a can soda drink itPress the middle downPoke holes in the middle with the very tip of a knifeCut.a hole on the side for the carbPut ur herb over the.holes in the middlePut ur finger over the hole.on the sidePut your mouth over the drink hole, suck in while lighting it then take your finger off the side.
I have smoked from a plastic bottle and its just like a bowlAfter you take your first hit, to clear the chamber you simply let off the hole by your thumb and suck in with a short hard breathAfter that the herb should be cherry and you can just replete and enjoy! Relight when neasicary as usual.
