Jonathan, Paul Rowe, and I built a miniature hot air ballon from a trash bag and powered by heat from Sterno. We were amazed at how well it worked. Unfortunately, it was really windy the day that we launched the balloon, which made it more difficult for the balloon to fly. We think the trash bag balloon would fly much better on a calmer day with little or no wind.

Final successful launch of the balloon:
Also, we had a nice adventure at Waterworks when we were launching the balloon. Jonathan was driving, and he thought it would be a great idea to park in the field. But, the car got stuck in the mud. So, Paul and Jonathan had to push the car while Cassie steered. After a lot of effort, we finally got the car unstuck.

Jonathan is triumphant after successfully getting the car out of the mud!
Jonathan, Kelly Hanken, Paul Rowe, and I built a tennis ball mortar from three Pringles cans, and then went to Waterworks Park and shot a tennis ball from it.

Amazingly, the tennis ball mortar worked great on the first try! Unfortunately, we do not have a video for the first launch, but we do have a series of videos of our varying degrees of success. We found that we had to wait a little bit after shooting the tennis ball for the fuel and smoke to clear before attempting another launch. Otherwise there was too much fuel in the mortar, and the tennis ball did not launch.
Last spring Cassie, Paul Rowe and I did something I’ve wanted to do for as long as I can remember- find historic photos and then photograph what’s there now. All of our shots are of downtown Des Moines. Most of the images come from the awesome Historic Des Moines collection hosted by Drake University. We also found neat historic images here and here.
6th and Locust looking south, in 1911 and 2009.
I can’t believe Des Moines got rid of those trolleys! Recently the city proposed putting in a much more limited tram system at a cost of $100 million. Des Moines looked a lot more lively in a hundred years ago 🙁 Shopping still existed downtown, and there was even a cafe!
9th and Locust, looking east. 1959 and 2009
Much of modern downtown Des Moines consists of alternating block-long office buildings and and block-long parking garages. Its good to see so many corporations downtown, but after 5pm this area is a ghost town.
10th and Locust looking East, 1979 and 2009
Wow, Des Moines was a total dump in the 70’s. It looks so much better now. The brick building on the left is the temple for the performing arts. It has been beautifully restored!
Polk County courthouse, looking North, 1911 and 2009
This picture just about makes me want to cry- the beautiful lawn in front of the courthouse has been replaced with a parking lot and a massive steel fence, the brick building in the background has been replace with an unbelievably ugly garage, and the gorgeous building on the right has been replaced with…. a parking lot! The trolley, the horse drawn carriage, and the pedestrians have been replaced with cars. I think if the Parthenon had been located in Des Moines, it would have been bulldozed to clear space for parking lots
Looking East from Des Moines Public Library, 1914 and 2009
The building on the left is city hall. The new building on the right is Embassy Suites. Other than that the riverfront hasn’t changed much.
Looking west across the Des Moines river from city hall. The building on the other side of the river is the old central library.
8th and High (1914) - the most prominent building remaining is St. Paul's, to the left of center. If you look closely you can also see the copper dome of First United Methodist Church in the background. The brick building to the left of the dome is Iowa Methodist Medical Center.

1940s - Shopping for Christmas at Walnut and 6th. Sadly all the shops long ago left downtown left for the suburbs. Now its pretty empty.
It’s kind of unfair to compare photos of today with photos of 100 years ago. Those photos were taken of the best looking spots of the city 100 years ago. Its understandable that they may not be the best looking spots now. Any list of the most scenic spots in the city today would certainly include spots that were total dumps 100 years ago. Still, its sad to see how much of the city has been gutted in order to suit the automobile and make people’s commutes a few minutes shorter. With a little more foresight the city could have been more people-centered and less car-centered. Fortunately city leaders have woken up to this, and new projects like the East Village and the Brenton Skating Plaza are great places to spend time. The government even ripped out the parking lot at the state capitol and replaced it with a garden!!
