The declaration in this action of tort contains two counts. In the first count Olga E. Evangelio, hereinafter called the plaintiff, seeks to recover for injuries she sustained by the explosion of a bottle of carbonated beverage alleged to have been negligently manufactured by the defendant; in the second count the plaintiff’s husband sues for consequential damages.
Findings of an auditor, to whom the case was referred under the usual rule, include the following: The defendant was engaged in the business of manufacturing and distributing a carbonated beverage called Pepsi-Cola. In the sale and distribution of its product, the defendant’s employees used motor trucks from which sales were made to “various tradesmen and storekeepers” who sold it at retail. In “the course of such sales most of the cases were piled on top of each other on the defendant’s trucks.” “From the time Pepsi-Cola was manufactured and bottled until delivery to a purchaser this beverage and the bottles containing it were in the. sole custody and control of the defendant.” There was no evidence as to who manufactured the bottles or as to how they were made. There was no evidence relating to the degree of carbonation of the beverage, or as to its ingredients or with respect to the process or care employed in its manufacture.
The plaintiff’s husband owned and operated a variety store in South Boston in which he sold Pepsi-Cola at retail in bottles. The plaintiff frequently assisted her husband in running the store. On March 16, 1955, while the plaintiff was in charge of the store, an employee of the defendant delivered two cases of Pepsi-Cola. The employee deposited *179 these cases in the rear of the store, “one on top of the other,” and received payment for them from the plaintiff.
About fifteen minutes later, the plaintiff picked from the top case two bottles with her left hand and one bottle with her right and proceeded toward an ice box fifteen feet away. When she reached the ice box she deposited therein the bottles held in her left hand and while in the act of depositing the bottle held in her right hand, it exploded and injured her hand. The bottle exploded before any part of it touched any part of the ice box.
From the time the cases were delivered at the store until the accident the plaintiff was alone in the store and during this period nothing had touched the bottles other than the handling of them by the plaintiff as above indicated.
The auditor, after finding the foregoing facts, left the question of liability to be determined by the court and assessed the damages to which the plaintiff and her husband would be entitled if they should prevail on the issue of liability.
In the Superior Court, the case was heard by a judge solely on the auditor’s report. The plaintiffs moved for judgment on the auditor’s report, and the defendant did likewise. The plaintiffs’ motion was granted and that of the defendant was denied, subject to the defendant’s exceptions. The correctness of this action presents the sole question for decision.
The plaintiff offered no evidence of a specific negligent act or omission as the cause of her injuries. The issue, then, is whether an inference of negligence on the part of the defendant could have been drawn from the fact that the bottle exploded, coupled with proof that it was handled properly after it had left the defendant’s control. In cases of this character the question is normally phrased in terms of whether the doctrine of res ipso loquitur applies. See, e.g.,
Roscigno
v.
Colonial Beacon Oil Co.
In essence, this doctrine, however denominated, merely permits the tribunal of fact, if it sees fit, to draw from the occurrence itself of an unusual event the conclusion that it would not have happened unless the defendant had been negligent. It does no more than recognize that negligence and causation, like other facts, may be established by circumstantial evidence. The nature of this permitted inference has been stated with clarity and succinctness by Lummus, J., in
Roscigno
v.
Colonial Beacon Oil Co.
Our first inquiry must be whether the explosion of a bottle containing a carbonated beverage is the kind of occurrence which usually does not happen in the absence of negligence. Neither of the parties has offered evidence as to the specific cause of the explosion. The burden of proof as to this matter, of course, rests on the plaintiff. She is not required to exclude every possible cause for her injuries other than that of negligence; she is only required to show a greater likelihood that her injury was caused by the defendant’s negligence than by some other cause.

The question presented is not one of first impression in this Commonwealth. In

Recovery was also denied in

opinions relied in part on
Burnham
v.
Lincoln,
*182 The defendant relies heavily on the Howard decision. There is no significant difference between the facts of that case and those here. Thus if that decision is to be followed the defendant is entitled to prevail. However, we think the time has come to reexamine the Howard case. Numerous decisions of other courts and a considerable body of comment and analysis by learned commentators since the time of the Howard decision have shed new light on the problem.
In determining whether there is a balance of probabilities in favor of negligence, resort may be had either to expert testimony or to common knowledge.
Roscigno
v.
Colonial Beacon Oil Co.
Numerous possible causes have been discussed in the cases dealing with exploding bottles, among which are (1) defects in the bottle, (2) defects caused by improper handling of the bottles, and (3) excessive carbonation. There are doubtless other causes. Most of the courts which have considered this problem since the time of the Howard decision have permitted the tribunal of fact to draw an inference that the explosion was caused by negligent conduct, leaving it to the defendant to explain why in a given case it was more probable that the explosion was the product of a cause for which the defendant was not responsible. Professor Prosser accurately summarizes the course of decision: "... [[TJhe
great majority of the courts now hold that [the explosion of] even a single bottle is enough to permit a finding of negligence.”

we are in accord with this position subject, however, to the qualification presently to be mentioned. To the extent that the case of
Howard
v.
Lowell Coca-Cola Bottling Co.
To recover in a situation of the sort here involved the plaintiff must prove more than the fact of the explosion. Where, as here, the accident occurs after the defendant has surrendered control of the instrumentality involved, it is incumbent upon the plaintiff to show that the instrumentality had not been improperly handled by himself or by intermediate handlers.

It follows that the judge did not err in allowing the plaintiffs’ motion for judgment on the auditor’s report.
Exceptions overruled.

Recovery, however, has been permitted in actions of contract based on breach of warranty.
Poulos
v.
Coca-Cola Bottling Co. of Boston,
In the early cases involving explosions of carbonated beverage containers a majority of the courts denied recovery. See
Stewart
v.
Crystal Coca-Cola Bottling Co.
However, a rapidly growing number of jurisdictions now allow recovery, if a showing of due care on the part of those other than the defendant who have handled the bottle has been made.
