To celebrate the 20th anniversary of our foundation, we organized several activities for our members and for our contacts. We have organized a family-day, where the volunteers of our foundation had the opportunity to show what they have been doing to their parents and siblings. There has been a reunion for all the old members of the foundation and an almanac was made summarizing the past 5 years of our foundation.
The family-day was a big success. As mentioned, all of the parents and siblings of the members were invited. We performed our Freezing Physics-show, the liquid-nitrogen-show that is traveling to high schools in The Netherlands to show that physics more than hard equations. The parents and siblings were also allowed to play with liquid nitrogen. A picture of an attendee (my own sister) is attached.*
The reunion was really fun and we think it was especially fun for our older members, most of them are not students anymore. There were also two of the founders at the reunion, which was a lot of fun for them. They didn’t know ‘their’ foundation still existed. A histogram is attached to show who were present at the reunion.*
We are very proud of our almanac. It cost a lot of work for the committee that was formed to produce it, but it was all worth it. Thanks to the Young Minds Grant it was possible for us to produce it for all of our members and contacts.
The family-day, reunion and almanac really made the 20th anniversary of the foundation an extraordinary year, for which we’re also thanking to the Young Minds Grant.

When the package arrived from Germany, we immediately knew what was inside. We eagerly, but carefully, opened the package to find inside what we had been hoping for. A coated YBCO superconductor, larger than any we had previously used. Naturally, the first thing we did was to fill a container with liquid nitrogen to test it. Once the superconductor was cooled to cryogenic temperatures, we were not disappointed. The magnet floating above it was more stable and could be mounted on a greater distance from the superconductor compared to previously used superconductors. Furthermore, the superconductor itself is shielded from the heat of the air around it, allowing it to be lifted out of the liquid nitrogen for a longer period of time.

Since the superconductor arrived we have visited many high schools in the Netherlands. There we found that the advantages of this superconductor as described above helped us to fascinated the students even more. With this new superconductor, we can properly demonstrate the levitating magnet, even to the students in the back of the class!

Most of our experiments are based on
elementary science, which the students themselves can understand. Therefore, they don’t expect us to show them something that baffles most Physicists. With this experiment we try to explain to students that Physics is not finished yet, and that still a lot of research has to be done to fully understand the world around us. Using this new durable superconductor, we have already sparked enthusiasm in hundreds of students, and will continue to do so for many years to come.
