So a tambourine is about an inch and a half and the moon is 238,900 miles from the earth, so 1.5 ÷238,900 is 159,266. That means that it would take 159,266 tambourines to reach the moon. A tambourine on amazon costs 15.99$. So multiplying this with 159,266 would equal 2,546,663.34$. Pewdiepie is worth between 30-50 million. This would mean that if Pewdiepie were to reach the moon, it would cost him 2.5 million and he could absolutely afford it.
