A mini-me and my sister at Olivander’s Wand Shop @ Universal Studios.

Growing up, I LOVED reading and watching the Harry Potter series.

Today… I still love the Harry Potter series. ⚡


Because magic is extremely fascinating to me and something else I’m intrigued by is technology.

One of my favorite quotes by Arthur C. Clarke says,

Any sufficiently advanced technology is indistinguishable from magic. 💫

Because it’s possible if we decide to create it today.

Let’s go travel back in time to book one of Harry Potter when we learned about the invisibility cloak. 🚀 (For those who don’t know what it is — it’s a magical cloak Harry [the main character] receives for Christmas that gives him the ability to appear invisible when covering him).
