The "Mind Maps: Stories from Psychology" exhibition in science museum

Today I went to science museum to have a look at "Mind Maps: Stories from Psychology" exhibition. These are some intriguing stuffs I found.

1. Avatar Therapy, using avatar to cure some people's illusion disorders..

2. Electromagnetic cage. Quite cult! This medicinal apparatus is just like barnacles. Actually there are many more medicinal apparatus like barnacles. I think I will make a collection next time.

3. Electrical belt for men. It is quite like some SM apparatus, frankly....Furthermore, it can even generate electric current...

4. A experiment proved the existence of animal electricity.

5. Frog pistol. Like a cult joke!

6. I have not yet utterly comprehended what it is....
