I make memories stay fresh, but I do not make memories themselves. People often wear me.

What am I? You mount your steed and prepare for a race, they look so focused with their painted face. the music begins and you start to give chase. After many laps you're still in the same place.

I'm coupled with a certain type of light, so pay attention to me! I also help your garden grow by controlling acidity. Add a slice or two of me to improve your culinary quality.

Born from one man's name but shared by all, I wear a tux though I don't attend the ball. I quietly run the web, your phone, your cloud, my code is open - contributors proud. Type a command and I'll bend to your will - what am I?

I am a room, usually wide I'm in a gun, usually holding the bullet You can see me in a revolver, but I'm also a place cleaned by maids
