💡 Everyday Comparisons for Size, Mass & Speed

💡 A maximum weight of 190 g is about the weight of three chicken eggs (Comparison).
💡 A maximum head-body length of 20 cm equals the length of a 20 cm ruler (Comparison).
💡 Its winter haypiles can weigh up to about 1.2 kg, far heavier than its own small body.
