Sounds to me like a revisit is in order make the ZF-3 next season.

dogfighting. having people who own antique aircraft let you turn them into laser tag game is totally cool.

epic food fight:
Tory is back to help take playing with food to the next level.
point: adam's first potato cannon.

Tory made a MAJOR engineering mistake, and I'm wondering whether it was a drama builder or just a lapse in thinking.

critique: more volume, less pressure, longer barrel. you'll see it when it comes up.

safety warning: watch for blast out of the cylinder gap.
protip: you know you've got a good arc if you can't test indoors.

I just rewatched the panjandrum episode and - although I had an idea for how to improve the design after the first time I saw it (single rocket in the drum, multiple nozzles on the wheels, which would have eliminated the problem of simultaneous ignition) - upon watching it again I realized that the whole idea was a bust from the get-go.
Why?
Because even if they'd solved the stability problem from rockets not firing in perfect sync or being misaligned, or if the flywheel setup had gotten it further, the whole thing would still have changed direction the moment one of the wheels had hit something that was slightly different in height or hardness from whatever the other wheel was in contact with at the same moment.
Let's say the left wheel hit a rock that just slowed it down slightly for even a millisecond while the right wheel was unobstructed and could have gone on in a straight line. Even in a best case scenario, that tiny impediment to the forward motion of the left wheel would at least have made the entire thing veer a little to the left, ultimately not hitting its intended target. A bigger or harder obstacle would have toppled it on its side, or maybe even have turned it 180 degrees and sent it back in the direction it came from. Scale that up to a beach in Normandy with countless bulges and divots in the sand, hundreds of Czech hedgehogs, miles of barbed wire and countless pieces of other debris lying on that beach (not to mention mines) and the odds of one of these things ever making it to the wall quickly approach zero.
In fact, the more likely scenario is that these things would have ended up on their sides within the first 30 feet out of the water. Some of them might have taken out a few mines and maybe flattened a couple of feet of barbed wire, but ultimately they would just have become extra obstacles on the beach that the soldiers and tanks would have had to navigate their way around.
I think a remote controlled Sherman tank with a huge V-shaped snowplow could have done a much better job of clearing a path.

I think a remote controlled Sherman tank with a huge V-shaped snowplow could have done a much better job of clearing a path. that was kind of my final analysis of the design as well. that design - as stable as it is at rest, becomes more unstable, the faster you propel it. the creative weapon I like from the era is the bangalore torpedo. it is about the opposite: slow, methodical, aimple, and effective. en.wikipedia.org/wiki/Bangalore_torpedo

An anti mine plough known as the “Bullhorn” was deployed and used on Sword beach. www.dday-overlord.com/en/material/tank/bullshorn-ploughIt was one of Hobart’s Funnies”.

I'm a bit surprised they didn't think to make a rocket sled.

I'm also aware of tanks being outfitted with what are essentially steamroller drums in front, the logic being that the hard, solid drum would just roll over a mine and blow it up.

The first flail tanks were Matilda tanks used at El Alamein in 1942.
This is more or less what happened when they tried to showcase the device to senior allied commanders. Said device hit a pebble and started to head towards the observers.
