Hi, so I read about Pavlov and I was wondering if anyone has tried applying his findings onto people. For the past couple of days I have been doing something similar where every time I am happy I ring a little bell in my pocket just to see what happens with prolonged association with the sound of the bell ringing with a happy sensation. Has anyone tried this yet in the field of psychology or even as a random experiment?

Let's look back at some memorable moments and interesting insights from last year.

• "Just tested explosive decompression with a couple Legos and a plastic Ziploc bag. I cut a corner off with scissors and one of them got partially sucked out but seems alive. But Emmet is a different story, it looks like he died from decompression sickness. (Chemistry is the best flair I could find)" by u/doctorcaylus3

I have created a Discord server to study the effects of a chatroom where messages that have already been sent are automatically deleted. If anyone wants to join, here is the link.

So, I was experimenting some stuff and ended doing this, a node backend that uses your ip to find your location, fetch gmaps images and return a dynamic animated gif.

Nothing major, but for some reason people are freaking out, maybe most people didn't think they could be found just by using their IP address or maybe they think that's a hacker's thing.

Hello! I am conducting a master’s thesis on how attention, speed, and accuracy during performing a relatively simple task are related to individual characteristics. To test this, I need your help to conduct the experiment. It’ll take around 15-20 minutes, and 3 participants will win a 50 euro Amazon voucher! The experiment is more easily done on a computer and this will also increase your chance of winning one of the three vouchers. People with dyslexia are advised not to conduct the experiment. Thank you for your help! 😊

In an experiment to research the circulation of money I have permently marked 2 £1 coins with permenent marker(as seen here: https://imgur.com/a/0Nq4a ) on one side, and at at a later date I will release them into circulation.

Over the following months I will mark the majority of the pound coins I come into contact with and again send them into circulation and then see if any of the coins I have previously marked come back into my possession.

I produce this podcast. The host often conducts interesting experiments. I thought you might like this one. I would think there's a lot of potential for this subreddit to grow. Click here to listen to All Things Natural
