I got three cows in cans…



The weakest sounding one got the can opener…



There was foam…



and a mysterious black cylinder…



Cracking open the base of the black plastic canister…



It’s a weight with a balloon tube taped to it… and a thin plastic disc…



It’s a blow toy/noisemaker in the weight! And air get sucked and pushed through it to make the noise!



Here’s a video - for you to hear the normal sounds… and see how that inside really works:
