How To Make A Cork Sink In Water?

To make a cork sink in water, start by gathering a few corks and ensuring they are tightly packed together. Use a waterproof adhesive or hot glue to bond them securely, forming a dense block. Once the glue has set, submerge the cork block in water; if it floats, you can add small weights or attach a net to keep it submerged. Ensure that the cork is sealed to prevent water from entering, which would cause it to float.
