Pim Linnebank at EditieNL - The Scent of Rain
Pim explained in the TV show why it smells nice after a rain shower when it has been very dry for a long time. The explanation is that organic substances accumulate in the ground and on plants, and that the rain causes these molecules to become aerosolized so that you can smell them.

Pim Linnebank at EditieNL - Steelfire
Pim was at the tv-program to explain that iron can burn and he did an experiment with steel wool, because it burns easily.

Pim Linnebank at EditieNL - Habemus Papam
Pim Linnebank was at EditieNL to explain how to make white and black smoke, and how this is done in the Vatican. In short, a powerful oxidizer is added to the white smoke, accelerating the combustion and formation of steam and small ash particles. To create black smoke, substances that actually burn poorly, such as anthracene or tar, are added, which results in incomplete combustion and therefore extra soot particles. This makes the smoke black.

Telegraaf and AT5 on the new method of detecting gunshot residue
Chemists from HIMS, in collaboration with AMOLF researchers, have developed a new method to detect gunshot residue. The new method ensures that released lead particles light up (literally). De Telegraaf has a news item about it, without comment from the scientists (Arian van Asten and Wim Noorduin) involved, but with an enthusiastic response from a forensic expert from the Amsterdam police. Also AT5 had an item on the new method of detecting gunshot residue, with Wim Noorduin appearing in a video.

Het Parool about the performance of the FNWI Ig Nobel team in NEMO
On Tuesday 15 April, Marc Abrahams, founder and organiser of the Ig Nobel Prize, will close the Ig Nobel Euro Tour with a festive evening at NEMO Science Museum. Het Parool looks ahead, with a description of the various speakers and their research. The Faculty of Science team that won an Ig Nobel last year is also present: Daniel Bonn, Antoine Deblais, Tess Heeremans and Sander Woutersen (IoP & HIMS respectively) received the prize for their research with drunken worms as a model for the movement of polymers.
