As Every Indian would know that there was a festival of Holi on 6th March. Also Know As Festival of Colours. I Hope Everybody Had Enjoyed Splashing Water Balloons On Each Other. But you might also know that after the day has passed we get Almost many Water balloons Left in our houses.
So, Let's Utilise Them into Making Our Aquariums Decorative! And Look Good.
Almost Every Child Loves. Balloons And i think that these Small Water Balloons will Look Great in our Aquariums.!

Step 1: Get the 3 Simple Things
1)Take 1 Packet of Water Balloons .
2)1 Reel of Strong Thread.
3)And 1 Vaccum Cup.
And we are ready to make it!
Step 2: Fill the Water Balloon
Fill the 3/4 Water Balloon with Water and Quarter with air.
Q1.So why should We Fill Air in it??
Answer: Almost Every Secondary School Kid Would Know About Density - Archimedes Principle .... And therefore You Would Know That Filling Some Air In the Balloon will Exert Up Thrust Force on Balloon . And the thread would always be Stretched. Like a Real Helium Filled Balloon.
Q2. Then Why Don't we Fill Full Balloon with Air.
Answer: Just to maintain a Decent Force on Vacuum Cup. // If we Filled the Full Balloon with Air then Vacuum Cup Would Always get Plucked Away from the Base.
Step 3: Tie the Vaccum Cup.
Here We Will Just Measure the length of thread Required to make Balloon Stay At decent Height.
And Tie one end to the Vaccum Cup.
So What i am doing here Is Creating Support for the balloon to keep it in Water ((Read Step 2 For Why.))
Step 4: Now, Tie the Balloon.
Now, Tie the Balloon with other End of Thread.
Remember : Always Tie the Balloon Above the Knot. This will prevent the thread from slipping from the Balloon.
Now Find a Place to attach it.
Step 5: Find a Place in Your Aquarium
Find a Place in Aquarium and Clear it so that there are no gravels lying.
Step 6: Attach the Vaccum Cup and Enjoy!
Now , Clean your Arms and Hands and Take the Vacuum Cup and Attach it to the Base.
Now Cover the Vacuum cup with Gravels and Impress Your Friends.
Add more Balloons Collectively to one Vacuum Cup.
