What is a place like a fridge or a box with a consistent high temperature where i can put a banana in for three days for my science experiment?

If you are looking at how the skin oxidizes, the temperature of you house would be just fine (it might take 4-5 days though), however, if it is warm where you live, you could keep it on the porch, or somewhere safe. If not, keep it near a window where the sun is prominent, or you could keep a box over a heat vent in your house (of course with a couple holes to let heat out), and put the banana in there.
