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.

Using a device, the ECN research center wanted to produce solar cells. The device could vaporize silicon onto solar cells, but unfortunately not with a density of the silicon that was high enough. As a result, the device lay gathering dust, until Christian Rood came across it and saw how useful the device could be for producing batteries.

Volunteers built a staircase covered with plants between the Centraal Museum and the canal in Utrecht. For three years, they worked with all their might on the staircase and the work of art cost 243,800 euros. Now a contract worker from the municipality of Utrecht has accidentally removed all the plants, not realising that it was a work of art.
