Did you know that the oldest glue in the world is over 8,000 years old and comes from a cave near the Dead Sea? Ancient people used this glue, made from a mixture of animal bone and plant materials, to waterproof baskets and construct utensils. Today, we have enough types of tape and glue to build and repair almost anything. But have you ever wondered what gives glue and tape their stickiness? Adhesives can be made from synthetic molecules or natural proteins and carbohydrates. In order to work, glue and tape need both adhesive bonds and cohesive bonds. Glue is stronger than tape in terms of absolute strength of adhesive bonds, but no single adhesive works well in all circumstances. Engineers weigh similar factors all the time. Choosing the right glue to withstand the heat inside an engine is a matter of life and death. And though the strength of duct tape's adhesive bonds can't compete with those of epoxy glues, tape does have the advantage of instantaneous stickiness in an emergency. Learning about adhesives can help you understand how things are constructed and repaired, and can even save lives in certain situations.

Concrete is the most widely used construction material in the world, but it has a weakness: it's prone to catastrophic cracking that costs billions of dollars to repair each year.

This technique has the potential to make concrete more resilient and long-lasting, which could drastically reduce the financial and environmental cost of concrete production. Learning about the science behind concrete and its potential for self-healing can not only be intellectually stimulating but also practically beneficial for the future of construction. Imagine being part of the solution to creating more sustainable and durable infrastructure for our cities.

Plastics have become ubiquitous in our daily lives, but few of us know the history behind this versatile material.
