For some of us, distances, and measurements are completely subjective! One metre, 10 metres, 500 g, 2 kg... just a point of view! And how good is your perception of space, distances and weights? This short test will try to test your perception. So let's see if your perceptions are accurate or not! Obviously we advise not to use aids of any kind while completing the test...
