Week 3, 'Pirates': Wednesday's experimentation!

Today, we've combined vinegar and bicarbonate to create one of the most typical elements in any good pirates story - sea foam! It was amazing to see it bubbling up!!
After that, we've learnt how to make a magnetic compass by using a sewing needle, a plastic bottle cap and a plate with some water. And we even started building our own origami compass! :)
