With the opportunity to undo Thanos' snap in Endgame, the heroes collects all Infinity Stones 1 / 10

But they needed a brand new Infinity Gauntlet to be able to reverse The Decimation 2 / 10

Which Stark provided them with using the resources and tech in the Avengers HQ 3 / 10

But how is that possible considering that Thanos had to go to Nidavellir to have his own gauntlet made? 4 / 10

Thanos, however, didn't care about the material that the gauntlet was constructed from 5 / 10

He went to Nidavellir for Eitri and his design abilities as a blacksmith which Thor pointed out 6 / 10

Given that, Stark only had to create a replica using the resources he had 7 / 10

Stark also had different encounters with the stone giving him an idea on how they work 8 / 10

In any case, MCU has established that "magic's just science we don't understand yet." 9 / 10

And Stark may have recreated the mystical capabilities of the gauntlet through advanced science 10 / 10
