With biomass plants, the government wanted to ensure that the climate targets would be met. The government set aside 10 billion euros for the construction of 628 biomass plants. Objections to the biomass plants soon arose: they would not be as CO2-neutral as was assumed and there would be more useful ways to use the biomass.

In 1905, the popsicle was invented by eleven-year-old Frank Epperson. He made a drink with water and some soda powder that he stirred through with a stick. Because his mother told him to go to sleep, he left the drink. When he woke up the next morning, it had frozen and the drink with the stick in it was frozen too. This was the first popsicle.

Columbus was looking for a faster sailing route to the Dutch East Indies. He planned to sail there via the West. With the financial support of the Spanish Queen Isabella, his ships left for the West, but instead of finding a new route to the Dutch East Indies there, he found the undiscovered continent of America.

Due to an accident at BP, a lot of oil unintentionally ended up in the sea near the Gulf of Mexico. In order to ensure that this would disappear more quickly, chemicals were thrown into the water that were supposed to make the oil droplets smaller and speed up the decomposition process. Unfortunately, the chemicals had the opposite effect: the chemicals caused microorganisms to flourish and drive out the microorganisms that were breaking down the oil.

Developing a good update does not always go smoothly. This went wrong for Windows 10, the Apple Homepod and Microsoft Office. The fact that everyone can configure their device according to their personal preferences makes each device unique, which makes it difficult to come up with an update that will not cause problems for all devices.

Hotline to Home was a telecom project with the aim of strengthening and maintaining important social contacts of hospitalised patients, using a combination of new technology and supporting communication volunteers. Unfortunately, it turned out that the patients involved did not understand the benefits of this project. The acceptance of video calls turned out to be low, contrary to theoretical considerations. Scarce personal contact was preferred to image calling.
