Stick to Sherlock!
Things I get overly excited in real life:
#1 CONCRETE TECHNOLOGY
On the left is the mortar without superplasticizer, on the right - exactly te same mortar, only with 2% (of cement mass) addition of superplasticizer. The whole mortar weights ~4kg, and 10-20g of superplasticizer can make it absolutely ‘watery’. It’s magic.
