A highly volatile explosive known as "mother of Satan" has been detonated in four controlled blasts at a property in Adelaide's north.
Police discovered a quantity of triacetone triperoxide (TATP) in a freezer in a shed at the Davoren Park house on Monday night.
Aaron Ellis was arrested and appeared in Elizabeth Magistrates Court on Tuesday charged with the possession and manufacture of explosives.

Police Acting Assistant Commissioner Craig Patterson said while the discovery was "extremely alarming" and investigations were continuing there was no evidence Ellis was planning a terror attack.
He said the 43-year-old had initially come to the attention of police in February after a post on Facebook in which he said he "hated Muslims".
Officers went to his home but found nothing suspicious.
However, further information received on Monday prompted them to return and to make the discovery in the shed.
"The accused may have some right-wing nationalist, anti-Muslim views which are being further explored," Mr Patterson said.
"But, at this point in time, we're stating that it's not a terrorism-related incident.
"There are no indicators of any violence or threats of violence to any member of the community.
"I can reassure the public that we have no information that this person was making a threat or was intending to use violence against anyone."

In opposing bail for Ellis, Brevet Sergeant Daren Cross said the chemicals found on his property had been referred to as "mother of Satan".
He said police had concerns that if released there was the potential for the accused to continue his activities.
But defence counsel asked for Ellis to be released on home detention bail, arguing he would not pose a significant risk to the community.
A decision will be made next week.
Ahead of the controlled detonations, bomb squad officers determined the material was too dangerous to transport from the scene.
They removed the TATP from the shed and placed in an area in the backyard of the property.
The area around the home was sealed off and neighbouring properties evacuated.

Other locals were warned to stay inside and away from any windows.
One resident, Linda, who did not want to give her last name, described the discovery as "really scary".
She said any explosion could have impacted on a wide area.
Another, Tony Schuit, said he had never noticed anything out of the ordinary about the house.
"It's certainly concerning," he said.
