Only one question is presented to this Court: whether the Court of Appeals erred in holding that the trial judge committed prejudicial error in allowing defendants’ motion for a jury view of *433the fire truck. We conclude that the Court of Appeals did so err and, accordingly, reverse.
[1] Although it did not expressly so state, the Court of Appeals evidently treated the jury view of the fire truck as an experiment. It applied the rules governing admissibility of experiments to the facts and found that the trial judge’s ruling did not comply with these standards. In treating the jury view as an experiment, the Court of Appeals erred.
After allowing defendants’ motion, the trial court instructed the jury:
All right. Now, members of the jury, at this the defendant is going to introduce into evidence for your benefit in this case the sound of the siren on a fire truck. This is going to be done in this manner. The jury is going to be taken as a whole in a body to a location out here beside the courthouse on Person Street where you will stand on the sidewalk. The siren on the vehicle will be activated and the vehicle will proceed from the location where it is to a point equal — or to your location.
Now, during this time, you are simply to listen, to observe the truck. This is not in any way intended to duplicate the conditions that existed at the time on —as they were on the 29th of January of 1980, but is simply to allow you the opportunity to hear the siren under the circumstances and the conditions that it will be presented here on Person Street.
During this time that this is being presented to you, you are not to discuss it among yourselves or with others who may be there at the scene, but simply to listen and to observe the truck.
As to what then happened, the record shows:
(The fire truck proceeded to approach the jury coming down Person Street with lights on and siren sounding. The truck passed the jury, after which the following proceedings were had.)
COURT: All right. Jurors will return to the courtroom, please.
*434Neither counsel nor the court regarded the exhibition of the fire truck as an experiment. The rules governing the admissibility of experiments contained in Mintz v. R.R., 236 N.C. 109, 72 S.E. 2d 38 (1952), and 1 Brandis on North Carolina Evidence § 94 (1982) are not applicable to the facts of this appeal. See also State v. Mayhand, 298 N.C. 418, 259 S.E. 2d 231 (1979).
[2] The evidence placed before the jury by the jury view was relevant and competent for at least two reasons. First, it was admissible to illustrate the testimony of the witnesses. Illustrative evidence is competent to enable the jury to understand the oral testimony and to realize more completely its cogency and force. Hunt v. Wooten, 238 N.C. 42, 76 S.E. 2d 326 (1953). Various witnesses had attempted to describe the flashing red lights and the sound of the siren.
Defendant Bullard testified:
The light on top of the cab is a round circular light, measuring about 12 inches across and it has four lights in it. It throws out a red light and twists around a circle.
. . . The fire truck had flashing lights on it. It’s got two in the grille or mounted on the front of the truck. It’s got one mounted in the center of the cab that measures about 12 inches across. When I say “cab” I mean the front of the truck, the cab, the part you sit in. The light is located right in the center, it is on top of the cab and there’s two on the tail end of the truck mounted on the sides.
. . . The light on the top of the cab, when I turn it on, rotates around in a circle. It emits a red light and it goes around in a circle. . . .
... I turned the siren on the high-low frequency. It’s two sounds, it goes up real loud, then back down, high-low.
The witness Forney testified: “The red light was spinning, flashing, and the siren was screaming. The siren from the position that I was standing was very audible, and I was able to see the flashing light.”
*435Donna Nunnery testified:
On the morning of January 29, 1980,1 was at home doing the wash, depending at what point in time you mean, I was in and out of the house. While I was doing the wash that morning, I heard a fire truck’s siren when I was outside hanging up clothes in my back yard. . . .
... It goes “woo, woo, woo.”
David Royal testified: “On January 29, 1980, I was at the crossroads store, the Bethany Grocery Store. . . . The lights were flashing on the truck. ... I heard the truck’s siren as it approached the intersection.”
Here a proper foundation was laid for the jury view because all the evidence indicated that the identical fire truck was available and that the flashing lights and siren were in the same condition as at the time of the wreck. State v. Barfield, 298 N.C. 306, 336, 259 S.E. 2d 510, 533 (1979), cert. denied, 448 U.S. 907, 65 L.Ed. 2d 1137 (1980); Hunt v. Wooten, supra, 238 N.C. 42, 76 S.E. 2d 326 (1953).
The evidence being illustrated by the jury view was relevant concerning the issue of whether the parties had complied with N.C.G.S. 20456(b) and -157(a) (1978). These statutes require a motorist to yield the right-of-way to a fire truck that is giving a warning signal by appropriate light and by siren audible under normal conditions for a distance of not less than 1,000 feet. Funeral Service v. Coach Lines, 248 N.C. 146, 102 S.E. 2d 816 (1958). The evidence produced by the jury view was competent for consideration by the jury for the purpose of illustrating the testimony of the witnesses concerning the appearance of the fire truck, the red flashing lights, and the sound of the siren.
The trial court is not required to instruct the jury with respect to evidence admitted for illustrative purposes in the absence of a request to do so. State v. Rupard, 299 N.C. 515, 263 S.E. 2d 554 (1980); State v. Cade, 215 N.C. 393, 2 S.E. 2d 7 (1939). Here plaintiffs failed to so request, and they cannot now complain that they were hurt by the introduction of evidence whose thrust they may have been able to limit.
The jury view of the fire truck was also competent as real evidence. “Real evidence, in the strict sense of the term, is that *436which is furnished by producing the thing itself for inspection instead of having it described by witnesses.” 1 Brandis, supra, § 117. The fire truck played a direct, actual role in the collision which is the subject of this lawsuit. It is real evidence. State v. Oliver, 302 N.C. 28, 52-53, 274 S.E. 2d 183, 198-99 (1981); State v. Harbison, 293 N.C. 474, 238 S.E. 2d 449 (1977). Although the trial court did not make findings of fact with respect to the motion for jury view, the evidence fully supports the court’s exercise of its discretion in determining the identity of the fire truck and the unchanged condition of the flashing lights and siren. Id.
Plaintiffs argue that the jury view of the fire truck was prejudicial to their case. This may be, but that does not make it error. It is not a valid ground for objection to evidence that it tends to prove the fact in question more conclusively when the object itself is exhibited to the jury instead of being left to the description by witnesses. State v. Brooks, 287 N.C. 392, 215 S.E. 2d 111 (1975). Evidence will not be excluded simply because it may have undue weight with the jury. Id. “ ‘Whatever the jury may learn through the ear from descriptions given by witnesses, they may learn directly through the eye [or ear] from the objects described.’ ” Id. at 407, 215 S.E. 2d at 122 (quoting 1 Stansbury’s N.C. Evidence § 117 (Brandis rev. 1973)).
This is true even though the object, such as a fire truck, is too bulky to be brought into the courtroom. It seems reasonable that the size of the courtroom should not necessarily limit the evidence to be presented to the jury. In State v. Taylor, 226 N.C. 286, 37 S.E. 2d 901 (1946) (a case decided before the adoption of N.C.G.S. 15A-1229 (1978) which codified jury view in criminal cases), this Court upheld the allowance of a jury view of an automobile in the courtyard. See State v. Smith, 13 N.C. App. 583, 186 S.E. 2d 600, cert. denied, 281 N.C. 157 (1972); Toler v. Brink’s, Inc., 1 N.C. App. 315, 161 S.E. 2d 208 (1968). The concept of a courtroom without walls is not new. 1 Brandis, supra, § 120. In fact, one remembers with some nostalgia presiding over hearings in the Superior Court of Clay County on the tree-shaded courthouse lawn in summer! Whether to allow the jury to leave the courthouse to see and hear the fire truck was a matter in the sound discretion of the trial judge. Huff v. Thornton, 287 N.C. 1, 213 S.E. 2d 198 (1975); Paris v. Aggregates, Inc., 271 N.C. 471, 157 S.E. 2d 131 (1967). The exercise of discretion by the trial court in *437granting or denying a jury view will not be disturbed on appeal in the absence of gross abuse. Huff v. Thornton, supra; Paris v. Aggregates, Inc., supra; 75 Am. Jur. 2d Trial § 74 (1974). We find no abuse of the court’s discretion in allowing this jury to see and hear the fire truck.
Again we note that plaintiffs made no request for limiting instructions with respect to the jury view. Plaintiffs did request instructions on other matters, and at the conclusion of its charge, the court gave counsel another opportunity by inquiring, “Anything further, gentlemen?” Plaintiffs’ counsel responded "no."
We find no prejudicial error in the granting of the motion for the jury view of the fire truck and, accordingly, reverse the decision of the Court of Appeals.
Reversed.
