Tell us about yourself!
I used the Grundig 38216 headphones, don't think they are available anymore. In hindsight I would definitely take some more expensive headphones as the Grundig ones are definitely not the best quality...
Indeed, but you shouldn't put them in the freezer. Our refrigerator is set to about 5 degrees celcius which is just about good for the chocolates. Definately don't get it below 0 degrees celcius (32 deg. Fahrenheit).
I would add them to the cream and then to the chocolate filling.Directly with the chocolate might not work well...
Thank you! Indeed the sound is much better. I was pleasently surprise by the warm bass that comes out of the headphones (but it makes sense as the wood is a lot better at damping than a 1mm plastic shell)
Interesting idea! Unfortunately there's almost no space for fill in my current design. Good idea for a new pair though :)
Haha, Thank you! I completely agree. In hindsight I would probably have bought a more expensive headphone. The sound quality is fine but the padded strap and fit of the earpieces is just cheap...

I made the standoff cardboard boxes a little bit lower (~5cm) than the COG. But it would be interesting to experiment with the placement and see the effect of it...
It is indeed a rounded number. For producing a reasonable size pyramid the 5th decimal will be much smaller than then the error in your cuts.
Thank you for your comment!I think it would be interesting to look at other shapes. However, as the pyramid shape is most often found in literature It seemed like a good starting point (starting the experiment not expecting a difference). However, if at some point there would be reliable proof for pyramid energy, then I would certainly like to see the effect of different shapes. Knowing the golden ratio to be a fundamental part of the pyramid geometry, it can also be intersting to look at icosahedrons / dodecahedrons, as they are closely related to the golden ratio as well.
I can imagine! Here in the Netherlands they don't sell good bar clamps, so I'm planning to make some as well. Did you experience bending in the end plate near the handle (with the nut in it), it seems like it could possibly bend when applying a lot of clamping pressure?
Homemade Bar Clamps
Thank you! That is a really clever solution with the threaded rod on the back. The best DIY bar clamps I have seen so far!
Well, but apparently you have to be a scientist to be curious enough to think about phenomena that other people just debunk based on what they think, instead of looking at facts.
Thank you for your comment!I completely agree. As this instructable is written after my experiment, of course it is biased. However, when starting the experiment, I did not believe a pyrmaid should or could have any influence on the results. I think it is most important to at least start the experiment being open for whatever restult comes out. Starting an experiment to prove it does not exist can never work. Why would you do it carefully if you don't want it to work...?
Thank you for sharing the intersting reads. However, they don't seem to prove pyramid energy does not exist. To prove it does not exist one also needs to do experiments, however when starting with the idea that it does not exsist, I don't think anyone will do the experiment carefully and in a controlled way.
