Rubik's Cube

Today is my rest day. I took my kid's Rubik's cube and play around. I used to be able to consistently solve it within 3 minutes when I was a kid. I think my personal best was around 1 minute 28 seconds. But I started slow with about 18 minutes. I keep playing to get familiar with the Layer-by-Layer solution method and improve my time. Finally, after about 2 hours, I have improved to 2 minutes 47 seconds as my today's personal best!! Next target will be to break my own personal best record!!
