How can you grow mold on a piece of bread?

Leave it in a warm, moist environment for a few days. It helps if you use bread that has no preservatives.

Take a piece of bread and sprinkle it with a tiny bit of water. (Bread goes bad faster in the summer due to the higher humidity)Place in ziploc bag and put in a dark and warm place. Look at it in a few days and you'll find mold growing. Natural breads without preservatives will sprout mold faster.....

Put the peice of bread in a dark place for abput 2-4 weeks

get it wet, put it in a sealed plastic bag, and hang it in the window. you could hang a dry piece next to it to compare the differences if you want to. observe over the following few days and probably in 2-4 days you should see some mold on the wet piece

Leave the bread in the wrapper,put in a warn moist place and let it sit for a few days MOLD WILL GROW!!!!!!!!!!!!

soak it in water, and let it sit for a week, mold will grow

No - take the front piece out, and placed the loaf in the refrigerator. it is the moisture in the packaging alongside with the warmth on your section. only examine to ascertain if there is any once you're removing a slice.

Simply by puting it in a ziplock baggie for about a month and wallaaa you've got yourself a science project!

Leave it in a warm moist place.

just leave it set out in the wrapper, it will turn all green
