Review on 🏆 Uncoated Regular Density Champion Sports: Optimal Performance for Sport Enthusiasts by Kaveen Restoration

I bought this styrofoam ball for a science experiment. It's called "cannonball". You drip some isopropyl alcohol into a tube that is capped at one end. Fill the foam ball on the opposite side. Rotate the tube to allow the alcohol inside the tube to evaporate. The tube has a small hole in the side towards the closed end. You shoot it and it shoots out a styrofoam ball. I tried this several times and it worked fine. The ball is soft and returns to its original shape after squeezing and releasing. I loved her. They look exactly like the picture but without the brand logo. It's only yellow.
