How can you use wine corks to build a stable boat?

In our 2nd installment on using cork for science, we investigate how to use cork to build a stable boat. In this case, we are referring to a small, toy boat - not one someone would actually sit in. Try building your boat in various configurations and decide which build you think makes it the most stable. Do you have other ideas? If so, build them and see if they are as stable as you had expected.

The Cork Harvest: The People

The cork harvest, a fascinating process, has deep roots in tradition and family. It involves the careful removal of bark from the cork oak tree which, when done with the necessary care and precision, does not harm the tree. In fact, the bark grows back time and time again throughout the tree’s lifespan. This careful process wouldn’t be possible without the highly skilled individuals in the cork harvesting industry. The precision and experience of the cork cutters make this process so successful.

Cork Trees: CO2 Sequestration & O2 Production

We know the cork oak tree is amazing for many reasons, the most popular probably being its ability to grow back its bark after each harvest. What may not be known is the crucial role the cork oaks play in both CO<sub>2</sub> sequestration and oxygen production. Cork trees, like all trees, absorb carbon dioxide through photosynthesis, storing carbon in their roots and branches while releasing oxygen back into the environment. So, what makes this tree different from other trees?

A little bit about the Jelinek Cork logo

The Jelinek Cork logo has undergone several transformations over the years. The most recent logo was designed, approved and put into action in 2008. Michal Macko, a graphic designer in Bratislava, created the logo as an entry for a logo design competition. The competition was developed by Korok Jelinek for the University of Graphic Design in Bratislava, Slovakia.

The Jelinek Cork logo symbolizes many things:

  • The tree represents the cork oak tree – the source of cork.

  • The tree also represents nature and the environment – issues Jelinek Cork Group cares deeply about.

  • The tree branches represent deer antlers and the Jelinek name. In Czech, the word “Jelinek” means “little deer”.

  • Finally, just as cork is stripped off the tree and then regrown, so are the antlers of a deer – they are shed each year and then regrown.
