https://en.wikipedia.org/wiki/Logic_gate
Hello everyone. I am searching for a little gadget - a simple logic gate with some transistors showing how a boolean operation works. Do you know some gadgets which perform those operations? I want to buy a device that performs a boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. I did many searches on Google, but strangely, I did not find any toy I wanted.More there are OP types, the better it will be. Thanks for your help. Below you can find a video which shows what I am searching :

Do you have a breadboard?
In videos like (https://www.youtube.com/watch?v=peCh_859q7Q "D latch" by Ben Eater), he constructs things from simple logic gates.
In the description, you can see the physical components he's using.
Search for those to see their datasheets.
For example, the 74LS08 is a chip that contains 4 AND gates. That's 3*4 + 2 = 14 pins total: 4x(2 input pins, 1 output pin), with VCC and GND.
One site to buy such components is digikey, but this is not an endorsement.

Thank you @Ganado for the links which are really interesting. This is an alternative - I can do my own gadget. However I have no experience with electronic. I will take a look at this opportunity. Thank you ++
If you just need/want to learn how these things work then you could consider on-line circuit simulations. They let you build circuit simulations that mimic physical components.

A simple/inexpensive gadget would be one made up of a battery and light bulb with handmade switches. No transistors needed.
See for example:
