Well its been a while since I have updated the change experiment and to be honest I am never going to be a scientist at this rate... anyway. The last deposit was made in March, so I do have a lot of change collected, $170.00, which does not help my interest much whilst its sitting in the saving tin. Should really be doing this monthly. Since then I have earned another $5.60 in interest and with the deposit I made today I now have $466.21 in the bank. I will endevour to make more frequent trips to the bank in future I promise.
