Our design challenge was to keep the water in the mug as hot as possible for 10 minutes, me and my partner started with different ideas for the design challenge, and then we had an agreement that we will use my partners idea as the prototype, and finally we started to build our design.

If I did this again I would be more efficient because I was sometimes goofing around in this design challenge, another thing is I should start the building process more earlier so I and my partner can have more time to develop and change.

I learned that we should use our time wisely, because our design turned out terrible. the heat started from near 90 and dropped to 69 degree in 10 minutes, so I think I didn’t use my time well.

one limitation I thought was that the water in the mug had to be drinkable anytime before, in, and after the testing 10 minutes.
