The escaped particles are negative charged and eventually coalesce into positive charges and heats up the room. But first they charge outside of the glass tubes negatively.
The tube is re-orientated to accommodate the particles that escape,
the tube itself need not be redesigned but only made longer, considering how far the particles have traveled from the future and how much Earth has moved then, Eastward.
To see the particles outside of the tube, discharge the tube at the air discharge voltage. Assuming that the discharge is due to nitrogen gas \(N_2\) in the air at \(78\%\), \(Z=7*2\), density \(1.165\,gcm^{-3}\) and molar mass \(28.01286\,gmol^{-1}\)
\(V_{min}=\cfrac{1}{2}\cfrac{M}{qN_A}\left(3.4354*{density}*{Z}\right)^2\)
\(V_{min}=\cfrac{1}{2}\cfrac{28.01286*10^{-3}}{1.602176565\text{e-}19*6.02214129e23}\left(3.4354*{1.165*0.78}*{2*7}\right)^2\)
\(V_{min}=2.7728\text{e-}4\,V\),
electrode gap \(d=1\,m\)
And for a gap of \(12\,\mu m\),
\(V_{min}=23.11\,V\)
