Tonight, he pulled it out to work on an experiment. Tonight's experiment was using taco sauce to clean pennies. Simple, but fun!
I found the grimiest pennies I could find and some extra packets of taco sauce.
Put a few drops of sauce on each penny and rub in. Let sit for 5 minutes, then wipe off with paper towel.
Our first attempt left a somewhat dirty penny. But our second attempt yielded a bright shiny penny! Look...it's from 1973 and it looks good as new!
We like Steve Spangler's Science for fun hands-on learning activities.
