England, a country built on brick designed to retain heat, experienced a historic heatwave last month. Having experienced the blistering 37°C/98.6°F peak myself, there's little I would not have done to escape that heat—even donning a silly-looking personal cooling wearable didn't seem beyond the pail.
Hardware channel Making Stuff with Mike is based in Denmark, which has also experienced its share of record-breaking heat. So, the YouTuber created a "functioning art piece" to keep him cool during the in-tents heat of BornHack 2026. The 'art piece' in question is a hard hat with an unusual centerpiece jutting out of it: A mini-chimney with a 120 mm Noctua fan mounted on top (via Hackaday).
