Are you ready to meet a design that you won't believe at first glance and that seems to overturn the laws of physics? The Anti-Gravity Table, which we frequently encounter on social media and at science festivals, actually contains a tremendous balance of engineering and physics behind the illusion of being suspended in the air.
We have compiled for you how you can do this wonderful STEM activity, which develops children's mechanical thinking, balance and problem-solving skills, at home with simple materials, and the scientific secret behind this magical structure!
"Anti Gravity Table" or scientifically known as Tensegrity (Tensegrity Structure); It is a structural system in which solid parts remain in balance without direct contact with each other, only by the pulling (tension) force on the ropes or cables. In short, this coffee table does not resist gravity; On the contrary, it locks itself in the air using gravity and the tension in the ropes!
You don't need complicated tools to make your own antigravity table at home. Here are the basic ingredients:
The secret of this project is hidden in the tension of the middle rope connecting the bottom base and the top base.
You can give your kids a great physics lesson while explaining why this coffee table won't fall.
Secret of Balance: The upper platform actually wants to fall down due to gravity. However, the short rope right in the center prevents the upper platform from falling down (holds it up). The ropes at the outer corners prevent the upper platform from swaying left and right and tipping over.
When all the strings are tightened at the same time, the pulling and pushing forces cancel each other, creating a fascinating static balance.
Engineering Skills: Children gain a great structural architecture experience by seeing how millimetric length changes of the ropes affect the balance.
Patience and Focus: Equalizing the tension of the strings requires patience; This increases children's focus time.
Abstract Thinking: They learn to establish a cause-effect relationship by seeing how objects can stay in the air without touching them, just with the power of the ropes.
In addition to being a great scientific object to decorate children's rooms, the anti-gravity table is also a great alternative for school projects. With a few popsicle sticks and thread, you can revive one of the most aesthetic rules of physics at home.
