If you look closely into the soldier's horn, you can see a couple of pink soap bubble wands. There are actually several of these mounted on a wheel that rotates the wands into the soap, and then air blowing through the horn makes the bubbles. You used to need to get your kids to make the bubbles, but automation has now taken that job away. It is not known whether blowing soap into the air was meant soley for decoration, or to double as an air purification system.
