My Biggest success is hot glueing the transparent plastic wrap. My biggest obstacle is to glue the plastic wrap with the cardboard. with the cardboard together.  Something I learned bout myself during the invention is that I didn’t give up. My invention is to keep food warm when you don’t want to eat it or else you have to heat it up again.  it looks like a transparent cylinder but it keeps the warmth inside. My project is made of transparent plastic wrap, foam tubes, cardboard.
