Introducing our 

Super Star Scientist of the week...

Luka Burciu!

 

Luka had his materials ready...

a penny, a cup, and vinegar

Luka showed us a dull penny and explained that the oxygen in the vinegar could clean it.

We could see the vinegar starting to do its job!

After a little rubbing with the vinegar, Luka showed us a shiny penny!

Way to go Luka!

We enjoyed your experiment!
