This is a way to teach them about recyclying and make a cool canteen in the process.
This project will take about 5 minutes to complete for adults and 10 - 15 for boys 1 - 6 grade (cause you gotta help them and they got you outnumbered 2-1 usually).
So here we go.
Step 1: Step 1: Get Some Stuff
A Square of tin foil big enough to wrap your bottle in
2 old (and preferably clean socks)
A legnth of string or rope
1 plastic water bottle
Go get it!
Back so soon?
Ok, lets get going then!
Step 2: Step 2: Sock It to Me!
Step 3: Step 3: All That Glitters
This will help hold the foil in place.
Step 4: Step 4: Sock It to Me Part Dos
Don't fold the top of the sock this time.
Step 5: Step 5: Tie Me Canteen Down Boys
Tie your string around the neck of the water bottle as shown and then tie the loose ends of the string together to form a loop.
Step 6: Step 6: All Good Things...
This will keep cold drinks cold for some time (or on a hot day for about 30 minutes or so).
Kids love it, it's fun to make
Parents love it, it's free
And it is useful.
