will heaven ever become boring?

Boredom could never happen there. It has wonders and beauties way beyond the amazing things the earth has to see and do. And 5 years here is like 5 minutes there. Time doesn't exist. Think of all the historical figures that came before us that you could meet. The laughter and feasting will be beyond imagination. And YES there will be food in heaven. 

WE DO NOT GO TO HEAVEN AS EARTH HAS BEEN GIVEN TO MAN, THERE WILL BE LOTS TO DO ON THE NEW EARTH SO U WILL NEVER BE BORED.

We live on one planet in a large universe that God created.
God created a large universe for us to explore. The eternity will be so much better than what we have now.

1 Corinthians 2:9 "But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him."

You can't even enter unless you are also trying to get everyone to obey Mat. 5:48 GT.

GOD has a wonderful purpose for humans. He created the first man and woman, Adam and Eve, to live in a beautiful garden. His purpose was for them to have children, to make the whole earth a paradise, and to take care of the animals.​—Genesis 1:28; 2:8, 9, 15

Do you think that we will ever live in a paradise? Jehovah tells us: “I have purposed it, and I will also carry it out.” (Isaiah 46:9-11; 55:11) Yes, he will do what he has purposed, and nothing will stop him. Jehovah says that he created the earth for a reason. He “did not create it simply for nothing.” (Isaiah 45:18) He wants people to live all over the earth. What kind of people does God want to live here, and for how long? The Bible says: “The righteous [or, obedient] will possess the earth, and they will live forever on it.”​—Psalm 37:29; Revelation 21:3, 4.

Since it doesn't exist its moot.

The word boring is only being used in this world , since pleasure , enjoyment and boring subject to time and change , since the worldly time is for temporary. But the life in heaven and hell is permanent , so pleasure and enjoyment in heaven would continue eternally but boring , suffering, tormented that being filled in hell , would cotinue for hell dwellers forever too.

Why are you stressing over God's ability to keep His children occupied and happy? "What no eye has seen, what no ear has heard, and what no human mind has conceived-- the things God has prepared for those who love him" (1 Corinthians 2:9). So, whatever you know today about "reality" is probably useless in Heaven. Consider that God spoke the universe into existence that consists of 200 billion trillion stars in a universe that is 92 billion light-years across. Have you ever looked at the images of space and the myriad formations of stars, galaxies, nebulae, gases, star farms, etc? God created the plant and animal species that number in the tens of millions, Why, then, do you worry that God will not be able to "keep you amused" or satisfied?

It might be boring.  Also, consider the fact that Lucifer was a fallen angel.  That means that angels can fall, even once you make it into heaven.  I wonder if someone could reform in hell?
