i have some questions about Metal leaft electropscope:-how to construct a simple 1?-where will the negative charges and positive charges go?-why will the aluminum foil leaves open?-where do the e- go and why?do i have to put conductor and insulator in it and why?
depends how long back you're looking atwax paper and general paper in the more recent historycloth before thatleaves before thatand earlier than that there wasn't much wrapping and moving food from place to placeyou just ate things fresh from the tree/vine/bush or cooking fireremember the days?plastic and aluminium feels like the worst options, doesn't it?
it truly is solidyet, given which you wrap it in some layers of plastic wrap or a ziploc bag firstconfirm you push out as lots air as a risk, then tightly wrap with aluminum foilit truly is going to help avert freezer burn prolonging the existence of your foodstuff productthere is not any asserting how long it truly is going to certainly finalIt relies upon on your freezer and what your freezingpurely bear in strategies maximum critically to push as lots air out as a risk while putting in a bag or plastic wrap first.
Wax paperI remember those daysWax paper was itThat's what everything was wrapped inIt came in the same carton as the aluminum foil and Saran wrap that you see today.
Wax paper was popular but if you go right back you will find that they used animal skins to wrap food in.
There are lots of plans online, see belowThe electroscope works, reacts, when too many charges are placed on its conductive surfaceIt's a bit like crowding too many people onto the metroSince similar charges repel each other the light weight leaves will push apart.
