Just thought I'd share something I made today.
Chopsticks (the ones you get at take-out places will suffice)
Card of some sort (I recommend a petco or petsmart card because their thinner than a credit card)
Total Cost: $0
Time to build: About 5 minutes (writing this thread took longer)
Step 1: Gather materials
Step 2: Cut the wide end with the razor
Step 3: Bend the razor to slip the wood
Step 4: Insert card of choice
Bigger Petsmart card
In action in my new Fluval Chi that I picked up yesterday during Black Friday at Petsmart
And it floats!
Thank you for taking the time to read through the thread
