Für dieses kleine Experiment braucht es nicht viel. Ein wenig Seifenlauge und die entsprechende Außentemperatur. Minus 25 Grad hat es in Hamburg allerdings äußerst selten, ich werde mich also mit diesem Video des Kanadiers Chris Ratzlaff begnügen müssen. Besser würde es bei mir vermutlich ohnehin nicht aussehen.

20 Sekunden Zucker für die Augen.

When it gets really cold outside, all you can do is have some fun with it. At -25C/-13F, soap bubble mixtures freeze faster than they pop, making for some very fascinating effects! When it gets this cold, I can often be found outside my house, bubble blower in one hand and camera in the other (I think my neighbours have gotten used to this sort of behaviour by now)

However, frozen bubble are still very fragile creatures, so I’ve experimented with different recipes to create a durable bubble wall that won’t pop in the slightest breeze; dish soap for the bubbling, corn syrup to thicken the wall and sugar to help crystallization. I let the mixture chill in the freezer to help speed up the freezing once outside:
– 200ml warm water
– 35ml corn syrup
– 35ml dish soap
– 2tbs sugar
– chill in the freezer
