First of all I would like to credit krazy glu with the whole concept. This is how to make a necklace with soda tabs.
Loads of soda tabs(100+ probably)
A large safety pin
Step 1: Start Collecting
You're going to need ALOT of soda tabs. I used 94 tabs, but my neck is really small so you should probably get as many as possible. I would say 100+.
Step 2: Cut N' Bend
Now you're going to need to cut the soda tabs so you can put them together. So take your multitool and select your pliers. I think the best place to cut is the little crease in the tab. Refer to the first picture for futher explaination on the crease.
Cut 4 tabs on the same side then bend each one. Try to bend the same amount for each one.
Step 3: Connect N' Bend
Now take 8 cut tabs and seperate them into two piles of 4. Slip one set of 4 into the uncut part of the other set. Refer to the picture for futher explaination.
Now bend the cut part back on the set you put through the hole.
Step 4: Make the clasp
Add links to the chain until it will fit comfortably around your neck.
Now take your safety pin and your multitool, and cut the pointy part off of your safety pin so that you don't accidently stab yourself while putting on the necklace.
Put the safety pin through the hole at one end of the chain and put the other part through the other end.
Step 5: AND BAM!
Now you have an awesome necklace. Now go out and have strangers ask you about it.
