Dimetylpolysiloxane

 

"Would you like Silly Putty with that?" They may as well ask that the next time you go through the drive-through, since dimetylpolysiloxane (a type of silicon that's used to make Silly Putty and breast implants) is also used in deep fryers to keep the oil from foaming, thus allowing the oil to last longer before it needs to be replaced. It's also used as an emulsifier and caking agent.
