This was fun! I want to know, did you just randomly weight the objects you found or look everything up on the internet? And now I know how terrible I am at guessing weight :D
Thanks for playing! I'm glad you had fun with it. To answer your question, it's a bit of column A and a bit of column B. All the food weights where found online and everything else I weighed myself. Honestly, a lot of the weights were a surprise to me as well :)
