Bread Bubbles

This experiment is about bread. If you have used my website for long, you know that I like experiments with food, especially when it is tasty food. We regularly bake bread, and there are few smells that are better than the smell of freshly baked bread.

Thoughts on an Exoskeleton

Tarantula and molt
My Brazilian Salmon Pink Bird-eating Tarantula (Lasiodora parahybana)

My pet tarantula molted this week, which started me thinking about exoskeletons. While we have our skeletons on the inside, other creatures, such as spiders, insects, and crabs wear their skeletons on the outside of their bodies. What would it be like to have your skeleton on the outside instead of the inside?

While we tend to think of sucrose (table sugar) when we hear the word sugar, there are actually many different chemicals that fall into that category. As we will see, different sugars have different properties.
