I've bought acid twice. Both in sugar cube forms known as 'triple drops' down here. The first time I had the acid I had a great night with mates in Melbourne city. I had 2 of these acid cubes. Great visuals. I was listening to dubstep, overlooking Flinders Street Station on top of a building my mates and I snuck up on. As the music progressed, the cars and people down below started moving faster and faster to the beat of the song trailing colours behind them as they went and slowed when the music slowed. When the 'bass drop' came the whole scene just exploded into a million different balls of colours, still all dancing to the music. Crazy shit. But the second time I bought the acid cubes I had 2 again, but nothing really happened. Just mind tripped. Wasn't as fun.
