Which Keeps Things Colder - Plastic Wrap Or Aluminum Foil?

Without any doubt, aluminum foil keeps things colder than plastic wrap. This fact had a very interesting logic behind it. 

Aluminum foil because its molecules are tight that makes it colder than plastic wrap and also because
plastic wrap is transparent which makes heat come through the glass and makes it hotter

Aluminum foil  is a metal and metal is good at conducting
[the reason metal is cold is because when you touch it  ,it absorbs your heat energy and it feels cold].

Plastic wrap is what keeps things colder because its surface is very dense which means it can absorb more heat more easier than metal

so the answer is aluminum foil

It's aluminum foil. I know this also because I'm doing a science experiment for my school right now.

Aluminum foil is denser than plastic wrap and I think it's a type of metal, which sorta absorbs more cold air from the fridge which keeps the item colder.

Plastic wrap is great to keep food fresh, though!

Aluminum foil because its molecules are dense than the plastic wrap.

I know its aluminum!!!!

I don't think either one makes much of a difference when it comes to keeping something hot or cold - they are both just too thin to have any measurable effect.

That said...

I think that aluminium foil would be more effective in keeping something cold because:
1.  It is thicker.  Thickness makes it harder for the outside temperature to penetrate and influence the temperature of the thing.

2. It is made of metal. Metal is a material that holds temperature. It slowly becomes room temperature, while plastic just loses heat/cold.

The reflective factor prevails here with the aluminum, definitively!

I think the aluminum foil keeps it cooler

Aluminum foil is the one that keeps thing colder !!!

Aluminum foil definetly!

It would be aluminum foil because aluminum is metal and metal holds temperature!!(temperature the object is;hot or cold)

Aluminum foil because it does not produce heat then it will keep the food colder

Aluminum!!!That's true!!!

It is aluminum foil.

I also think it is aluminum foil

It would be plastic wrap because aluminum foil is probably made of some metal and some metals contain heat

I think both because if you put them in the fridge you get cold wrap and foil

Plastic because plastic is an insulator and the coolness will stay inside

Aluminium Foil is the answer to this one.

I think it would be aluminum foil because of that its metal and if it can make things hot than it can make thing cold

Plastic wrap because plastic doesn't conduct heat as well as aluminum foil.  Aluminum foil will help make the food as cold as the fridge faster than plastic wrap.  But once you take the food out of the fridge, food in plastic wrap will keep food cooler than food in aluminum foil because the aluminum foil will absorb heat more quickly than plastic wrap.
