Tripped Over Again and Again

In the previous blog about the marble run machine, I have written, "I have not yet jumped over the first hurdle. " After that, I jumped over the first hurdle!
Yes, I did, and I tripped over it and fell. Well, that happens all the time.

 

I fell because I could not figure out the difference between the virtual and the physical worlds. I always draw pictures using 3D software when I make something. Mine does not have a function of physics simulation, so I must imagine how it moves when I make it.
It is not difficult to see a collision detection. I can simply rotate or move an object I want to make sure. However, there is a more complicated phenomenon, like friction or gravity.

Do you think I should buy a more superior one?
Well, I agree, but you know, it is costly.

When making a marble run machine, I have one system that I do not want to remove. That is the most difficult mechanism.

Yesterday, I made some samples to make sure whether they moved the way I wanted. It was like a school physics class. I regret that I should have studied physics hard. It took time and effort, but it was worth experimenting. Now, I understand how they work and the effect of friction. I was going to make small parts, but now I have changed my mind. I am going to make bigger parts that would be more stable.

I know you cannot guess what I am talking about. I am afraid I cannot tell you the details until it is finished. I am going to create a unique marble run machine that will not disappoint you when you see it.

The Fact I Didn't Want to Realize

The puzzle that my husband and I have been working on since July last year has finally been completed. I deeply realized it was easier to make linear objects, but it takes a long time to make things like animal shapes.

Since we have been busy, the backyard and roof of our house haven't been maintained well enough. So, we got things tidy last week. I was in charge of the garden beds. My husband did a cleanup of the roof gutters.

We knew one of the gutter ends always overflowed when it rained. Probably, it had got a lot of fallen leaves inside. Then, he took it apart from the gutters. He just pulled it, I saw one giant frog drop from the gutter end. It was a big Australian green tree frog.

He/she dropped to the ground and looked quite grumpy, making a noise. Then, we found ten more frogs in the gutter end. All of them were Australian green tree frogs. Maybe, they were going to hibernate there. The frogs all looked unhappy when they were suddenly thrown out.
Sorry, mate.

I don't have the opportunity to see so many frogs, and I took some photos. I think they are cute, don't you agree? There was an unexpected encounter, but eventually, we were happy that we could clean it.

However, I believe an easy, happy ending wouldn't make the story interesting, would it? I wouldn't betray your expectations. The story hasn't finished yet.

On the night of the cleaning up, we had dinner feeling well. The gutter end won't overflow anymore. It's a crisp feeling!
Just at that time, my husband suddenly said, "Didn't you notice?"
"Notice what?"
"There were frogs in the gutter end which means, you know?"
I finally realized an awful fact.

Rainwater runs into the gutters, and gutter ends. Then, water goes into the rainwater tank. Can you guess why we are keeping rainwater in the tank? It's for drinking!
Yes, we have been drinking the water after the frogs had bathed. I also noticed worse things. They don't go to the toilet like us, do they? That's disgusting!
What we recognized was quite awful, disgusting, foul, or whatever the vocabulary I have cannot express well enough.

Today's blog post has nothing to do with puzzles, yet it was a bit of a gobsmacked fact, so I have written about it.
Before I end today's blog post, I should say this.

We are in pretty good health status, thanks.
