Gonna find out how heavy Naruto and Boruto's Rasengan was :P

I'm also gonna be using M=V*D

(Since I don't know the density of Chkara, i'm only gonna be using
the density of air since the Rasengan is a ball of spiraling chakra and wind)

Density = 1.225 kg/m3

Volume of Sphere = V= 4/3 π r^3

Height of Blank Period Sasuke = 1.82m (According to Naruto Wiki)

Sasuke Pixel height = 223px

223px = 1.82m

1.82/223 = 0.81cm/px

1 pixel = 0.81 cm

Rasengan Pixel Radius = 180

180*0.81 = 145.8 cm

Rasengan real radius = 145.8 cm

Finding volume of sphere using 4/3 π r^3

Volume of Rasengan = 1.3e+7 cm3

M=V*D = 15.925Kg

Now im gonna calc the amount of energy needed to create something of this size
using E=Mc^2 (It's gonna give me a bloated result but this isnt meant to
be taken lightly since the main purpose of this calc is tpo find the weight)

E=15.925Kgc^2 = 1431267622138382092 Joules or 1.4e+18
