NORRIS, Circuit Judge:
Appellant Miguel Garzón appeals from a conviction for possession of cocaine with intent to distribute and conspiracy to distribute cocaine. He claims prejudicial error from a “conscious avoidance” jury instruction. We agree and reverse.

The evidence at trial may be summarized as follows. In March of 1981, appellant’s co-defendant, Moreno, met Weaver, who, unknown to Moreno, was a Drug Enforcement Agency (DEA) informant. Moreno and Weaver discussed the possibility of future drug deals. On March 25, 1981, Moreno told Weaver that he had located a seller of drugs. Late that night, Moreno took Weaver to a location in Inglewood, California where appellant and his father had adjacent homes on the same lot: appellant lived in the home in the front; the father lived in the home in the rear. According to Weaver’s testimony at trial, Moreno, the father, and appellant negotiated to sell four kilograms of cocaine. The discussions took place first at the front home, where the father showed Weaver a small amount of cocaine, and then at the rear home, where the father showed Weaver all four kilos of cocaine. Weaver testified that appellant was present during both displays.
Weaver then left, ostensibly to find purchase money. Instead, Weaver met with DEA agents to make arrangements for the bust.
The next afternoon, Weaver returned to the Garzons’ homes with two DEA undercover agents. The father met the three at the front gate and walked them to the rear home. On the way, the father asked appellant to join them in the rear home. Once the six had assembled at the rear home, the father left for a moment and returned with a package that contained cocaine.
One of the DEA agents testified that he and appellant discussed terms of the deal, with appellant limiting the sale to one pound of cocaine.
The father set the package down on the kitchen counter. Either at the father’s request, or on his own, appellant then picked up the package, opened it, and showed it to the DEA agents.
Finally, Weaver, the father, and one of the DEA agents left the rear home to retrieve the money. The father was arrested outside. Appellant was arrested inside the rear home with $1100 cash in his pocket. A subsequent search revealed a scale in the rear home, and a scale in the front home.
Appellant’s defense at trial was that he had no knowledge of any cocaine deal. Appellant denied involvement at the meeting the night before — a denial corroborated by testimony of his wife, brother, and father.1 Appellant testified that he joined the group during the next afternoon because his father requested his presence and he was loyal to his father. Appellant denied having had any discussion with the DEA agent about terms of the deal. Appellant admitted only to carrying the package across the room and opening it up to show to the agents.2

Appellant testified that the large amount of cash came from a job he had performed a few weeks before. The man who supposedly paid appellant testified at the trial and confirmed appellant’s story. Appellant also explained that he did not have a bank account because he was a recent immigrant from Cuba and did not “know the banks” and “all the money that I would get would be for like telephone and rent.” During cross-examination, appellant stated that he had the money in his pocket because “when I was arrested I was involved in taking some steps with my wife because we had talked about looking for a lower rent, or something like that.” Reporter’s Transcript at 349. Appellant offered no explanation for the scale found in his home.
