Pharmacy themed decorated cake

One of my friends was planning on giving a surprise birthday party to her husband. I and her take a walk sometimes. She started talking about it and asked what kind of cake should be made for his birthday. Boy, did she ask the question to the wrong person? I was there talking about the entire design of the cake during our remainder of the walk. She said she was amazed by the way I came up with the design, but I probably scared myself about how obsessed I am with these things. Anyway, coming to the point, her husband is into research in the field of medicine. There is a reason why I came up with the mortar and pestle design. They have a big curio full of different kinds of mortar and pestle collection. Keeping that in mind and the fact that he is into medicine, I made this cake.
Everyone loved it, I hope you enjoy it virtually too.

Everything is edible on the cake except for the mortar and pestle. That is foam cup cut to the height and filled a bit with fondant, covered with fondant and painted with silver color luster dust. Rx is food paint. Pestle is a bubble tea straw covered with fondant and shaped up.

Tablets are made out of fondant too.

Fondant scribbling paper with some calculations.
All in all, I had so much fun making this cake. The border is rosette at the bottom and reverse shell with wilton star tip 21 on the top.
Cake was vanilla sponge cake single layer with buttercream frosting.

Enjoy.
