How do you make Mexican jumping beans jump? This question has intrigued many people, especially those who are fascinated by the magic and mystery of these fascinating seeds. Mexican jumping beans, also known as “beans of life” or “beans of the devil,” are small, round seeds that seem to move on their own. In this article, we will explore the science behind the jumping beans and how to make them jump with a simple trick.
Mexican jumping beans are actually the seeds of the “Lablab purpureus” plant, which is native to tropical and subtropical regions of Central and South America. These seeds have a unique ability to jump or move due to the presence of a small, hard seed coat that allows them to expand and contract with changes in temperature and humidity.
Here’s how you can make Mexican jumping beans jump:
1. Prepare the Beans: First, you need to obtain some Mexican jumping beans. You can find them at most novelty or craft stores. Make sure they are clean and dry.
2. Heat the Beans: Hold the beans between your fingers and gently rub them together. This will create friction and heat them up slightly. Be careful not to burn your fingers.
3. Cool the Beans: After heating the beans, quickly cool them down by dipping them in a bowl of cold water. The sudden change in temperature will cause the seed coat to expand, making the beans jump.
4. Repeat the Process: To make the beans jump continuously, repeat steps 2 and 3. Each time you heat and cool the beans, they will jump higher and faster.
The reason why Mexican jumping beans jump is due to the unique properties of their seed coat. When the beans are heated, the seed coat expands, pushing the inner part of the bean upwards. As the beans cool down, the seed coat contracts, causing the bean to fall back to its original position. This cycle continues, making the beans appear to jump on their own.
While the jumping beans are a fun and fascinating phenomenon, it’s important to note that they are not alive and do not have a will of their own. The movement is simply a result of the physical properties of the seed coat and the changes in temperature and humidity.
In conclusion, making Mexican jumping beans jump is a simple and enjoyable activity that can be done with just a few basic materials. By understanding the science behind these beans, you can appreciate the magic and mystery of this unique natural phenomenon. So, the next time you come across a bag of jumping beans, don’t hesitate to try out this fun experiment and watch the beans dance to the rhythm of heat and cold!
