23% Isopryl Nitrate
23% diethyl Either
From this gentlemen’s other videos I’m guessing that he’s a erythritol tetranitrate kind of guy.
“The car demolition was basically an ANFO composition on steroids, swapping fuel oil for methanol and nitromethane (the two can detonate together at certain ratios), and adding large amounts of finely powdered aluminum and erythritol tetranitrate.
In this case the aluminum is the reason the charge is thermobaric- with the methanol and nitromethane, the charge was roughly oxygen balanced. The addition of the aluminum meant that the charge had to utilize atmospheric oxygen to complete burning of the aluminum, greatly enhancing the blast duration, overall pressure, and heat of the explosion.”
