It might be suggested before, but I think it's more than these. The problem:
1. For example, snowballs do just knockback. Ever mind to have ice balls, or obsidian water "bombs"? Or anything?
2. Ever wanted to get your obsidian without bucket and pickaxe, and with no chance of mistake of placement?
3. Wanted to enforce or weaken, or change color of something? The solution:
Refrigerator.
It looks like this:
As you see there are 3 pistons in empty bottles whose are jammed by slimeballs, plus triangular plate on it.
It must be powered by Redstone in order to work.
The Sense:
As you know if any particles do something they lose their energy(and temperature). Imagine pump(piston), pressurising air in Glass Bottle which is jammed with Slime in opposite side. The slimeball pops out and the air cools down, even water vapour cools, making "mist"
So, it looks like tripod with 3 cylinder glass bottle pumps and slime. And on the top of and between these pumps there is plate on which(in animation) you put chilled component and put the "target" inside.
There just like in furnace there are 2 slots:
The item is chilled and the component. Component is optional.
Once its started you will see animation of slime balls bouncing and piston extend-collapsing.
It will cool just like furnace heats.
You may reverse some(except food) of cooled items using furnace, but not hot items using cooler.
Food will just change form, for example beef into beef meatballs.
So after sucessful chill you've got affected target. If component is using bucket it will return a bucket.
Water/lava/milk buckets hold 25 uses and will "burn"(or, consume), even if top slot is empty,
Examples:
You wanted to experiment with fried meat. Without component it will give meatball, with bucket of milk it will give milky meatball, with lava bucket it will give fake meat, and with water bucket it will do nothing.
Meatball can be used to throw to your ally - it has extremely small knockback and restores 1,5 hunger with some saturation. Milky ones restore 2 hunger.
Fake meat will damage for 0,5 heart with each bite- you can never eat it.
You wanted your snowball epic. You put it in refrigerator with water bucket and got iceballs, they can be crafted to ice block, or into obsidian, which returns some water bombs(as water dissolves inside obsidian shell due to hot lava).
Water bombs will damage for 1,5 heart and reduce oxygen by 1, and cannot be thrown as rapidly as eggs or snowballs, also stacks up to 8
Water bombs can be crafted with sugar cane to make oxygen packs - they can be used underwater to "drink " air from them. They return water bomb because they fill with water(and sugar cane). Oxygen pack will restore 2 air bubbles.
Oxygen pack can be crafted into Air Vest and it will give you water breath for 10 seconds.
After water breath it will give you slowness because it turns to vest of water and needs to be decrafted to 7 water bombs,
Iceball damages for 1,5 heart and cannot be thrown as rapidly as eggs. Stacks up to 4.
They might be used to create ice blocks of simply more powerful golems, also for attack.
Also, Sugar Cane. It can be cooled with no components and then re-heated in furnace to make shard of sugar which will give you swiftness for 10 seconds and restore 0,5 hungerbars
It can be cooled with obsidian, then decrafted to make small pipe and obsidian branch. Obsidian branch can be used as obsidian explosionproof fence, and as weapon(1,5 heart melee) and small pipe might be crafted with 8 more small pipes to make piping block which is used to water plants.
Eggs can also be cooled without nothing to make monsterchicken egg. It spawns a normal baby chicken but with some data and no visible differences, and it will overgrow and attack anyone except monsterchicken just like Wither does, but including undead. They are made friendly to you if you give them gold nugget. They may be your guardians, or your enemies in your pen. Monsterchicken has 3x health normal chicken has and damages for 2 heart. Breeds without feeding and very fast, maybe twice per day. Watch them, make sure your guardian isnt making enemies.
They can be cooled with lava bucket, making them hard. They yeld no chicken but can be throwed without rapid fire but for 2 hearts, and drops as item on impact so can be reused. As a limitation they stack up to 4.
Snow block can be cooled with or without water bucket to make ice block, but with water bucket it makes 3 ice blocks.
Glass block/panel can be cooled without anything to enforced glass which has more blast resistance.
Glass with milk as component can be cooled without anything to make white colour block or pane, which can be craft-dyed just like leather can.
Redstone lamp can also be cooled to make frost lantern which has broader light distance.
Pumpkins cooled with lava make obsidian pumpkins, used as even better than diamond helmets, with huge durability and natural tendency to resist some fire.
Pumpkins cooled with water make frost pumpkins which can be woren for 2 more durability or can be torched to make even wider lighting. Torched frozen pumpkins or Frost Jack'o Lanterns have effect of block where is your head to emit light 7 blocks radius.
Frost pumpkins reflect light and can be used to reflect it like mirror.
Rotten flesh could be frozen, crafted and put as zombie scaring blocks whose inform undead their bodies will be frozen(they are afraid of that). They will not scare others.
