"As per the video floating around the internet where a portal was opened in a guys bedroom I have taken it upon myself to attempt to recreate the same thing. I was not able to open the portal visibly directly, but I had the speaker move around on me and I had an influx of orbs during the attempt. I believe there is a way to amplify the effects so I will continue to try and open it again."
using the online tone generator to create that hertz frequency that man in the video did to get that black blob up dident do anything here so what would a light source like tht do the same or not if not then theres something unknown missing in it all to get the same results
