Spirit Communication Tools that can be made at home..?

Hello!
I just watched an episode of Ghost Hunters where they used a "K-2 Meter" to detect ghosts and communicate. It seemed to work well, and I was rather convinced. However, K-2 Meters can reach 300+$, which I don't have.

Therefore, I would like to hear everyone's idea(s) on ghost investigation tools that can be fashioned at home!

For example, A simple pendulem in a glass jar that the spirit could swing. Another one could be, say, a precariously balanced item which could be tipped to fall by the entity.

If anyone else has gizmos like the sort mentioned, please, share!

 

Well there is the one where you take a paper bag and a stick. You beat the stick on the floor and say here spirit and the spirit goes into the paper bag. Although I haven't figured out what to do with it once it is in the bag.

 

Pop the bag probably..

 

Good idea.

 

You know how ghosts and spirits are supposedly drawn to electrical charges? All these ghost hunting shows that go into a house, deck it out with thermal cameras, night vision cameras, computer centre in the living room, static machines, emf readers, sound recorders etc then nothing happens and they try to prove that nothing exists. I've been thinking, if a shark can sense a pin prick of blood in any given amount of water and ghosts are seemingly engrossed with electrical charges, then if I was a ghost I'd be shit scared of all the electrical components suddenly in my haunting place! No wonder they never show up. They're probably hiding waiting for everyone to piss off and get their junk outta the place!
The supernatural world seem to be attracted to emotions. Because of this I recommend music tbh. Music is definite emotion charged with energy. If you can find a music that whatever it is your trying to communicate with can bond with then there's the opening. From my experience.

 

Very insightful, thankyou!
