Aluminium is a fairly common but reactive element. The cockroach is one of the most abundant species of beetle. Though in this case, we are talking about the European cockroach as I accidentally realized that cockroach was also a perfect match for Lead. Why? Well, we will get to Lead at another stage in the future (32 posts away). So Aluminium is an unforgiving element… Kindof. It is very malleable, changeable and if you treat it right, it will do the same for you. Treat it wrong, and it rots to the core. Much like what will happen if you leave European cockroaches alone!
Silicone is a rather interesting metalloid being one of the most abundant metals in our crust, its use in computing, glass, and many clays and ceramics is now well known; its separation as a single element, however, is relatively late in 1823.
Dragonflies often have four transparent wings, which often reflect the light iridescently giving them an almost seemingly magical glow. It is because of this glow that Dragonflies hold a significant place in some mythology and culture. Wetland loss, however, means they are now less common. Silicone and dragonflies both have this iridescence in the natural form, and thus they belong together.
