Time travelling

Eat, eat, eat

When we enter the dental materials lab, it's like we are timetraveling back to the 80's. Here we encounter some expired resin composites which are older than me.

The resin composite beams in various colors
We were curious how those expired resin composites will perform at the compressive test.

Ok so the compressive strength of the expired resin composites are way too low (red by CK and orange by Dane). The green one is normal not expired composite.

It was almost lunch time and we were hungry. Hmmm gypsum porridge should be ok...
We tested the tensile strenght of paper
Even dr. Matinlinna tried but we all failed. With this demonstration, dr. Matinlinna wanted to tell us what impact an imperfection in dental material can cause.



The three gypsum produced from one mix. First Dane made his perfect gypsum, Kylie made an almost perfect one and I made a Cheesy one. By the time I made mine, I think the gypsum was already starting to set. Because Dane's gypsum had the highest strength and mine was the lowest.
