I'm trying to make a spiked bat with nails hammered in a wooden bat. Obviously, I can't use wood, so I'm planning on picking up a plastic bat and painting it. But I also need nails. Preferably something flexible that won't break. I've heard about using drinking straws as molds and squeezing in some silicone caulk but my tests show the caulk is a little too thick to go in the hole evenly. I was wondering about latex, but not sure that will be strong enough or if it would fall apart. Would I need a rod in the middle to stabilize the nails? Also, how would I get them to stick to the bat? The plan would be to drill holes in the bat, but the plastic bat will likely be hollow giving me little surface area to glue them to, not to mention the issue with trying to glue a flexible material like silicone or latex.
