Is there anything more exciting than exchanging secret messages with friends?

The pen contains invisible ink that can be used to write hidden messages. They will be visible only with the help of UV light, which is located in the camera on the cap, where it is perfectly masked. Top Secret!

Suitable for little detectives, agents or anyone who doesn't want their parents to read their secret messages.

The PhänoMINT Solar Zeppelin is a simple yet fascinating science experiment that demonstrates the physical principle of buoyancy. It works best outdoors on a sunny, windless day.

One end of the 3-metre-long black balloon is tied with the included string, while the other end is held open to fill the zeppelin with air. Once both ends are closed, sunlight heats the air inside. As the warm air expands and rises, the giant solar zeppelin begins to float and can reach heights of up to 30 metres.

This hands-on experiment allows children to explore buoyancy and the behaviour of warm air while discovering why hot air rises and how the same principle makes hot-air balloons fly. The packaging also includes additional fascinating information about the science behind the experiment.

Features:

• 3-metre-long zeppelin-shaped balloon
• uses solar energy to heat the air inside
• can rise up to 30 metres
• string and spool included
• fascinating information about the scientific phenomenon of buoyancy included inside the packaging
• fun educational science experiment for young explorers

PhänoMINT stands for phenomenal experiments for curious school-age explorers. Exciting topics from mathematics, computer science, natural sciences and technology are presented in an accessible and playful way. Through hands-on experiments, children can discover the fascinating science behind everyday phenomena.
