First Day At Electronics

The Get Ready Get Thru website tells us there are three things we need to do to get ready for a disaster which are...
1. Have a household Emergency plan
2.Assemble Emergency survival items
3.Have a get away kit
It says I need a torch with spare batteries in my survival items. I am going to design and make an Emergency Light at Electronics. In my family we would need 90 litres of water all together because 3 litres per person and I have 10 people in my family so 3x10=30x3=90 litres.
