Goldfish help please?

ive seen a something like this used once and only once if u get a square water jug like the 3 or 4 gallon ones they sell at the store u can cut open the top and hang a filter from there and that way they are in atleast 4 gallons of water until u get home and can actually set up a real tank if u youtube videos i've seen what u call tupperware tanks 2 where they went out bought the completely clear 10 gallon containers like tote buckets and used them as a temp tank for a few months until they could get something more suiteable which isn't ideal but i mean if ur leaving school and going home hell it'll work as a temp thing. just get that fill it with water as high as it take to run a filter and hope for the best most of the clear tote containters are completely safe for that the colored ones not so much but then again ppl use them for sump tanks to thier 100 gallon tanks so who am i to judge like i said get a 10 gallon tote bucket put it under ur desk or something with a simple lamp to light it for 12 hrs a day and then just hang any old filter on the back of it or where ever it'll fit and that way if it's clear u can atleast see the fish and they should be good no need for gravel or anything just water a filter and a simple desk lamp to light the tank 12 hrs a day and ur good to go till u get home and can afford something for them.
