Since the graphic claims microchips are made out of “sand”, I will call silica “sand”. To get a spoon full of “sand”, some random internet sources suggests that it would weigh about 33g, and apparently oats is quite dense in “sand”, so youd need about 176 kg of oats, or about 27,000 spoonfulls of oats to satisfy your diet of “sand”. Impressive!

(Or maybe you just eat it raw as a anti-caking agent?)
