Bag of comedic timing

This bag has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. The bag can hold up to 500 pounds the mystery items don't count toured this total  . The bag weighs 15 pounds, regardless of its contents. Retrieving an item from the bag requires an action.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered up to 50ft . If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute but contains helium) affects last for d4 minutes , after which time they begin to suffocate.

Placing a bag  of  Comedic Timing  inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can’t be reopened.

unlike the bag of holding you can't just reach in for whatever you want and expect to get it. the bag also comes with a endless supply of random mystery items players must roll a percental die on a 100 you get exactly what you want. on a roll of a 50 or high you might get something similar to what you want but not exactly it has potential to be useful.  on anything lower you get something random and fairly useless like a balloon animal. you have a minute to use the item before it vanishes. on a 1 the bag explodes in a burst of confetti and whatever your looking for is lost to another plain all other items are scatter including a wide verity party decorations up to a 50ft.  creatures within rage of a 20ft radius take 8D6 force damage on a failed dex save on a success take half. the person holding the bag at the time of the explosion as well as anyone in it has disadvantage.
