How much weight to sink a block of ice ?

[sparkythecat]

If I have a cylindrical block of ice weighing 3kg, what's the minimum weight of lead thatI would need to add to it, to make it sink to the bottom of a pond 10m deep?

Excellent ! Thanks for your help chaps.

What does being cylindrical have to do with it?

Excellent username, given the topic in question

For those that are wondering what it's all about.
I intend to freeze some blocks of 'rubby-dubby' or chum (fish guts trimmings and slops)
They'll be moulded in small buckets, with a volume of around 3 litres. I wanted to know what size of lead weight to throw into the mix when I'm freezing them to be guaranteed that the blocks will sink. The lead weight , frozen in the mix will have a loop of line on that I will clip through a carabiner and slide down the anchor rope when I'm fishing off my boat. As the ice melts, the rubby-dubby trail will drift down the tide and attract fish under the boat.
The lead weight will be retrieved when the anchor is eventually hauled.
Yes I realise that frozen fish entrails are not the same density as ice and that seawater is slightly more dense than freshwater, but from the calculations you've done for me I recon that a pound of lead (454g)in each block should do.
Which is good, because I already have a good number of 1lb weights to hand

I need to know

Why are you doing this ?

Anglers love to experiment.
