In the center but not at the center of the cube

Yes, the string in the center will balance the top from tipping. The 4 outside corner strings give the top more stability from tipping!

You believe tensegrity is fake? You can make one like he did in like 5-10 mins try it out it's actually really cool me and my nephew did it totally recommend it 👍

@@shadcoe5326 I didn't say that optical illusion can't be replicated. It is a optical illusion, that is not how tension works...that's "technique" is relying on the strength of the main support and then adds like basically tassels, completely useless, to misdirect your attention. That's let saying that the Christmas tree ornaments and lights are what holds the whole thing upright when really it's the tree trunk...but on a great decorated Christmas tree you don't really want to see the tree trunk do you? All that "tensegrity" garbage all have a main support beam or pole or trunk or whatever, either way a main support, and it is nothing to do with the tassels if those were removed it isn't going to come apart like a suspension bridge. "Tensegrity" is bullshit. I wouldn't even call it clever, only the delivery presentation of how those people are showing it is impressively deceptive but that's only because they're using "infomercial" techniques. It's clearly bullshit. You'd have been better off having your child make a suspension bridge with toothpicks and or popsicle sticks or twigs and string or twine. And test the load limits if you like. At a Japanese University they use materials like that for their students to come up with creative designs for making earthquake proof/resistant skyscrapers and place those on a earthquake simulation shake table with weights placed on the model skyscrapers to test their durability and resistance to earthquake movements while bearing heavy [top] loads. They're all engineering students I think and they have it as a contest for them a with a grand prize like the newest Playstation or whatever.

Actually it is just nylon string under a little tension!

Yes, you need two compression components (stiff) that support the top and bottom of the table

To describe in simple words without any physics terms, the bottom plate is holding up the top plate. Or think of it as the top plate is hanging from the bottom one. The metal wires in the middle are the key. Take a second look and think about it for a minute, you will see. The wire coming straight up from the bottom one, that is doing all the muscle work, supporting the top plate. That top plate has its wire going down at an angle, to balance its weight as best it can in its center with the string. You could hang the top one from the bottom one with only the center string, but would need your hand to hold the top one steady to keep it from falling to one side. That's where the four outer strings come in. Like how a tent is staked to the ground, the guy ropes are tensioned evenly on all sides to keep it centered and upright. Here the four outer strings are taking the place of your hand to keep the top plate steady and centered, evenly tensioned.
