THIS IS HARD !!!

So I was flipping through my science stuff the other day and I realised that I've totally forgotten about my blog D: and checking the Project sheet I read that the first blog entry is due on Thursday and i havent quite started. so here I am, still thinking of ideas on what to do =="

i've got two ideas on what to do, which building design withstands earthquakes best? or Does an egg float or sink in water? What if we change the density of the water by adding a substance? E.g. Salt, Sugar.

hmm so i dunno, someone help me decide xD
