uxcell Foam Tubing for Handle Grip Support, Pipe Insulation, 25mm(1") ID 35mm OD 1m Length Black

Hi. Does it float?

I have a tool on a 1' od metal tube that i use with repeated force. is this product durable enough to use for a tool handle?

Can I use this foam to replace the handle on my push golf cart?

I want to use this for my koi pond, but it doesn’t say exactly what this is made from. Is it toxic to living organisms?
