Behind the scenes

Hi everyone,

this time, creating the new puzzle (the airplane puzzle) was very different from usual. Why? Because in March 2020, the lockdown due to Corona came, and we all had to work from home. But that didn’t stop me, of course 😉

And working from home on the balcony has its own charm 😉

I could no longer shoot the videos with our media producer Stephan as usual. This means I had to figure out how to shoot videos myself with what I had at home. So Stephan wasn’t there to hold the camera, and I didn’t have any accessories, like a tripod. But in true Kniffelix spirit, that you can experiment with household items, I experimented this time with how to shoot videos for a new Kniffelix puzzle using things from around the house.

I want to show you what I came up with and built for this with two little behind-the-scenes glimpses. Have fun watching!

And then I needed a solution to film the work on a suspended airplane…

Have you ever built a tripod from household items, or perhaps something else? If so, please describe it briefly in the comments or upload a photo of it. (If you are reading this report in the news, click on the title of the post above to comment.) I’m curious.

More aircraft models

Hi everyone,

Pia was particularly diligent with us and simply built several different airplane models. How are things with you? Have you ever built another airplane? Or do you feel like trying out more models? Whether made of cardboard, sticks and fabric, or a paper airplane, it doesn’t matter 😉 Be creative!

Upload a photo of your other model and tell us if it flew well.

Please briefly describe what you particularly enjoyed, what you learned, what you didn’t like as much, or what you would have wished for.

I’m very curious how you liked it.

Adjustment of the flyer

Hi everyone,

well, were your adjustments in building the flyer successful? Did you use playdough to shift the center of gravity, or another material?

Was it difficult to get the right amount of playdough or other material to place the center of gravity centrally over the wings?

What does your finished flyer look like? Feel free to upload a photo and share it with others.

And most importantly, how did the flying work out? How did the flyer fly now? Does it fly further if you throw it straight forward or slightly upwards? And did it work better with a lot or a little momentum?

I’m excited to hear what you report.

What is wrong with the airplane?

Hi everyone!

Well, did you spot the mistake? What’s wrong with this airplane? What can you see in the picture?

Do you know what else plays an important role when flying?

I’m excited to see what you observe!

What keeps airplanes in the air? – Your ideas

Hi everyone,

Airplanes are very heavy. Many people fit inside them and are transported at the same time.

So what keeps airplanes in the air, even though they are so heavy? Do you have any ideas yet?

I’m excited to see what you come up with!

Before you write a comment, please take another look at the rules of use.

Does your airplane model fly?

So, how did building the airplane work out for you?

And what kind of material did you use? Did it fly as badly for you as it did for me? Do you perhaps already have an idea what could be the reason???

I look forward to your observations and ideas.
