Hi,
I have found a video for you about a bowling ball cannon! Please don't try this at home. I wonder what the ground looks like where it hit. :-) They should try this for structure testing in modern buildings and cars.
Anyway, we have got some fish in our fish tank now, and it is very exciting to watch them, as they are rather wiggly and pretty funny to watch them attack their food as soon as you feed them. I will let Cora expound on the subject, so I will get off of it. We are making good progress on Andrew's grain cleaner, and Dad just bought himself a generator so he can get his going now too, but all in all the cleaners are coming along nicely.
Here is the video! (I suggest muting it, though the guy does say it goes across a river!)
Beware of flying bowling balls! I hope you have a great day.
Jacob
